Blogger reaction to filtering trial

August 3, 2008 – 8:00 pm

It’s been nearly a week since Conroy hailed the Tassie ISP filtering trial a success. Here’s an overview of what other bloggers are saying about it:

‘The mainstream media in Australia has been outraged by the Internet censorship in China, but seems to be paying no attention to its rise in their own backyard.’ - Coenraad van der Westhuizen, Thoughts into the Void

‘That censorship will no longer deliver 75% drop in speed doesn?t make 22-30% acceptable. Any cut in internet speeds places Australia at a further disadvantage in the information age.’ - Duncan Riley

‘The Minister for Immigration, Senator Chris Evans, has said he has too much power with regards to the decision of individual cases. I?m not sure that a subsequent conservative government would say the same over their powers to censor Australians? internet access.’ - Sam Clifford, Public Polity

‘It seems that Senator Conroy is acting at the behest of Family First Senator Steve Fielding and the Australian Family Association, and is on a bit of a moral crusade. Child pornography is the new WMD and it’s the argument being used to curtail Australian freedoms and to squash debate.’ - Sean, Sean the Blogonaut

‘Perhaps the most sinister part of this debauchery is the implications as to where our nation is heading. The only countries in the world today who have enacted such overreaching Internet filters are China, Burma and North Korea ? none of which are known for their high standard of civil liberties.’ - Ashley Kyd, Off Topic with Ashley

‘This situation is perfectly analagous to the Government legislating that the post office needs to start checking inside the envelopes for inappropriate material before sending them out for delivery. It’s a whole different business than just routing letters based on postcodes, and would require a whole new staff. (Just ask the North Korean postal service). If you can imagine how such a situation might slow down mail delivery, then you can imagine why network performance would drastically degrade if content filtering was mandated by the Government.’ - Colin Jacobs, NoCleanFeed

‘If such a system is implemented I believe the Australian Government will anger and frustrate many website owners both overseas and locally. Processing blacklist removal requests will be a major undertaking that will incur continuous monetary, time and implementation costs.’ - Simon Pascal Klein, Klepas.org

‘Beyond such issues about the wisdom and scope of government censorship, there?s also the question of whether such centralized filtering poses other concerns about the extent of government authority. Many people will be put off by the prospect of national governments playing the role of national nanny via centralized network filters. (Fill in your own ?Big Brother? or China analogy here). But many others will be left wondering what else such a move subsequently allows the government to do in terms of network snooping and surveillance. And there are other concerns here regarding the ongoing cost of the process (who pays for network upgrades?) and how else those resources might have been used.’ - Adam Thierer, The Technology Liberation Front

‘In other words, each time the filter blocks something there is an about even chance that it wasn?t porn. In my opinion this is sufficiently damning evidence to show the worthlessness of any of these filters.’ - Alastair, Girtby.net

‘I’ve been using a filtered ISP at my university (they’re running a trial) and what I can do online at home in one minutes takes the better part of fifteen at work.’ - John S. Wilkins, Evolving Thoughts

‘How long will the Rudd government continue to pretend that having this cumbersome, costly and ineffective product shoved at us under an opt-out scheme is in any way a good idea?‘ - Tigtog, Hoyden about Town

Victoria Police blame Internet as kids turn to crime

August 3, 2008 – 1:50 pm

When common contributors to youth crime like drug and alcohol abuse, poverty, and family dysfunction seemingly become impossible to combat, what can those responsible for fixing it do? In the Victoria Police’s case, you take a tired and unproven old excuse from the 90s and rewrap it: you blame the Internet.

About 10,000 Victorian children aged 10 to 14 have been cautioned by police, arrested or ordered to appear in court in the past year, as a surge in youth crime continues.

Victoria Police say the escalation in juvenile crimes ? ranging from break and enters to drug offences and assaults ? is being fuelled by children’s growing exposure to sexual and violent images on the internet.

[...]

The head of the police youth affairs office, Inspector Steve Soden, said too many children were viewing inappropriate content on the internet and this, coupled with boredom due to a lack of community services on Melbourne’s fringes, was behind the alarming rise in youth crime.

No evidence of a causal relationship between the two or proof that youth crime is even rising necessary; Just the word of one Inspector. The media never forgets how fun a witch hunt can be.

Space Chimps under review, Two Hentai films banned

August 2, 2008 – 8:43 pm

HamDoes anyone have any idea why Space Chimps is under review (PDF) by the Classification Review Board?

It’s currently rated PG (Mild threatening scenes) and though I’ve never seen the film, it seems like a reasonable rating for an animation about chimps in space. Maybe too harsh a classification, maybe not harsh enough? Who knows in this country.

Meanwhile, two Hentai films have been banned. Bondage Mansion and Holy Virgins were two of four Siren releases all rated R18+ in Australia, but after an application for review from Bob Debus (Minister for Home Affairs) was received, those two titles were banned (PDF).

Refused-Classification.com writes:

The result is two titles are banned, one has its consumer advice altered, and the other escapes with no changes. What the Review Board decisions confirm is that as long as none of the characters are portrayed as being below eighteen then it is okay to show hardcore sex in these features.

In June, EzyDVD was advertising Bondage Mansion in their latest releases section next to a Bob The Builder DVD. Sure you could blame the alphabet, but c’mon — the box cover of Bondage Mansion next to Bob was a bloody scary sight.

More flaws surface in clean feed trial

August 1, 2008 – 5:07 pm

Network engineer Glen Turner has voiced his concerns about the Tassie filtering trial. In the comments section of my earlier post, Glen says a critical flaw exists in the trial’s testbed design:

‘80-90% of Australia?s Internet traffic goes to the USA, a considerable distance and a large amount of latency. This is not simulated in the network design ? rather the testbed assumes that all the content is local to Australia and thus of low latency. Effects like jitter and loss become exponentially worse as latency increases, so the testbed understates by orders of magnitude the performance effects on traffic. This single error is so huge that its effect swamps the results, rendering the performance results of no value at all.

Glen also says that the trial focused on the performance of the Ethernet protocol, when it is the performance of the TCP protocol which dominates a user?s experience when encountering a bottleneck like a filter.

‘TCP performance is determined by latency, jitter and loss. Nowhere does the report measure the effect of the insertion of a filter middlebox on those essential variables. In short, these amateurs have measured the things that don?t matter and not measured the things which do.’

Why the Tasmanian filtering trial is a failure

July 29, 2008 – 8:42 pm

Senator Conroy ISP Filtering Trial A Failure

Senator Conroy’s office could spin a thread of gold from a lump of shit, I’ll give them that. But if you’ve read the Tasmanian filtering report, it probably didn’t take long before you noticed red flags. I decided to compare the report to what Mr Conroy says in his press release and show why the trial is nothing but a miserable failure.

What Senator Conroy says:? The performance or ?network degradation? for one of the tested products was less than 2%, whilst three products were less than 30% and two products were in excess of 75%.

What the report really says: The filter that showed less than 2% network degradation was also one of the least accurate filters at identifying illegal and inappropriate sites. The more accurate filters showed a larger drop in network performance.

What Senator Conroy says: Successful blocking (the proportion of illegal and inappropriate content that should have been blocked that was successfully blocked) was between 88% and 97% with most achieving over 92%.

What the report really says: It probably won’t take anymore than 12 or 13 clicks before a filtered user can access a site containing adult or inappropriate content.

What Senator Conroy says: Overblocking (the proportion of content that was blocked that should not have been blocked) was between 1% and 6%, with most falling under 3%.

What the report really says: Even if you choose the best result (1%), out of every one million websites, 10,000 will be be blocked when they shouldn’t be.

What Senator Conroy says: All filter products tested were able to block traffic entirely across a wide range of non-web protocols such as instant messaging and peer-to-peer protocols. However, most filters are not presently able to identify illegal content and content that may be regarded as inappropriate that is carried via the majority of non-web protocols.

What the report really says: The only way the filters could block traffic on non web protocols was to ban access to them completely. That means if you want to chat to Gran about her garden or drinking habit on Messenger, you wouldn’t be able to. No matter how innocent.

Those are just the starters. Here’s the main course:

1) Load testing was based on just 30 simulated users. Large ISPs have hundreds of thousands of customers and even small ISPs have thousands. Any network performance testing based off 30 users is not reliable when the plan is to filter every Australian’s Internet connection.

2) During the trial, only 3930 URLs were filtered. When you consider Mr Conroy wants to block ‘inappropriate content’ to children, 3930 URLs is simply too low and doesn’t show the potential real impact on network performance or filtering effectiveness. The Internet contains hundreds of thousands of websites not appropriate for children by our classification standards.

3) The report claims all but one of the six filters was able ‘filter’ HTTPS traffic. This is unlikely, considering HTTPS traffic is secure. The filters can probably only blanket ban access to such traffic. Nobody wants their banking and online purchases monitored by the Government.

4) There is no analysis of circumvention methods and that’s crucial to understanding why filters - ISP and software based - are ineffective. Filtering can be bypassed in minutes by a savvy net user and in hour by anyone following instructions.

5) There is no analysis of the costs of deploying and implementing a filter at ISP level, nor is there any analysis of the associated costs that will be passed onto customers.

That to me looks like a failure dressed up by a Senator with an obsession on controlling what you can and can’t see.

Visit NoCleanFeed.com to find out how you can take action. I for one wouldn’t want my blog or businesses website blocked for no reason.

Oh! If you spotted other doozies in the report, please post them in the comments. No doubt I’ve missed many.

Media reaction to filtering report

July 29, 2008 – 7:18 pm

It’s a shame that some major news organisations were happy to run a rehash of Senator Conroy’s can-do-no-wrong press release about the Tassie filtering trial report. Thankfully, not all media was so accepting.

In Crikey, Stilgherrian points out that even though the report found ‘most’ filters achieved over a 92% success rate in blocking sites, 1 in 13 naughty sites are not blocked.

Similarly, the “low levels” of overblocking (incorrectly blocking legitimate content) are, at best, still 1%. With more than a million registered domain names in Australia (a loose measure of “sites”) even a 1% false positive rate means 10,000 perfectly acceptable websites are blocked. That?s with the best product. Under ideal lab conditions. The least successful of the products tested was eight times worse.

And Stuart Corner for iTWire writes:

Perhaps the most significant limitation of the trial was that it was conducted with a simulated tier 3 ISP, one that purchases outbound transport from other networks to reach the Internet.

ACMA said that it was not feasible in the trial to assess how the performance results for the selected products might scale to a tier 2 ISP - one which directly peers on the same level of hierarchy but must purchase outbound transport to reach some portion of the Internet - or a Tier 1 ISP.

As the latter account for the bulk of Australian Internet customers, one has to wonder just how useful this trial has been.

I also had the opportunity to discuss what I thought about the report with ComputerWorld Magazine. You can read that here, but in short I expressed concern over the high false positive rate of the filters (1 - 8%) and the miniscule amount of URLs tested (3390).

Dale Clapperton from EFA said in the same article that the government needs to provide more information on what content will be blocked. He ‘expressed concern that the blacklists in the trials were set to ban all material rated from R18+ to a “strong” M.’

Conroy issues report on filtering trial

Update 29/07/08 2PM: I’ll post tonight about some of the problem findings in the report that aren’t making mainstream media.

Journos express anger at China’s net censorship

July 28, 2008 – 9:27 am

International news organisations in China preparing for the Olympic Games have gotten their first taste of net censorship. Word coming out is that journalists are finding news websites censored and Internet speeds up to 10X slower than those at the Sydney Olympics (that must be slow).

SMH writes:

‘Organisers had repeatedly claimed that internet would not be censored during the Games but at the press conference a Wall Street Journal journalist produced his laptop and showed that sites such as the BBC in China and Hong Kong’s Apple Daily were being restricted. BOCOG media director Sun Weijia initially said the problem lay with the journalist, and claimed all websites and pages were available.’

Q&A video game discussion: The clueless are out in force

July 25, 2008 – 8:04 pm

There’s no rating system for video games in Australia. Not my words — they belong to Q&A host Tony Jones. He’s sometimes referred to as a journalist, but in this case obviously not the type who does research.

We all know there is a very strict ratings system for games in Australia. It’s the bloody reason we are having this debate. That slipped past the heavyweights on last night’s Q&A panel though in favour of a giant stream of bullshit:

- Heather Riddout said people who played GTA turned into car-jackers (just not her sons)

- Baraby Joyce managed to somehow go from discussing games to rape and snuff films in a heartbeat

- and Nick Xenophon just wants to ban, ban, ban! Possibly even BAN!

Thanks to the awesome NoCensorshipAus channel on YouTube, you can watch the clip below.

Despite the misinformation spread by the panelists, an adult video game classification will not bring extreme violence and sex to our screens. Just like the R18+ for films, they’ll still need to be classified but now they’d be restricted to adults.

This is about taking a step out of the dark ages and understanding that censorship is not the answer to protecting anyone, especially our children. It’s about giving adult Australian’s the right to purchase video games that can be played as close as New Zealand. It’s time to grow up.
