This is a continuation of my previous rant about the proposed Australian mandatory ISP-level filtering.

The final problem I have with the filter is how what is blocked is determined. The blacklist is not public. It is not public because it can be bypassed and contains the addresses of illegal material. However, because it is not public, the public can not know what is being blocked. It’s kind of a lose-lose situation. If the blacklist is public, people who want to access the illegal material know where to go when they bypass the filter. If it is not public it raises freedom of speech and censorship issues: What if the government doesn’t only block illegal content, but anything it doesn’t agree with? This is proof that the filter can’t work: If it worked perfectly, the blacklist wouldn’t need to be secret.

Now to address the arguments of the people in support of the filter.

1. Porn is easy to find accidentally on the internet
In my experience porn is actually quite hard to come by unless you go looking for it or for other illegal stuff. This being the case, kids who find porn on the net were looking for it. Implementing a filter won’t help since kids who want to find porn will find it regardless – They generally know a lot more about the net than their parents or Stephen Conroy. Remember the 15-year old who broke the previous government’s filter in 30 minutes?

2. You can find kiddie porn easily on the web
I, who use the internet more than most people my age have not EVER come across kiddie porn on the web. The AFP said that most kiddie porn is transmitted using other protocols (P2P, email, VPN) than the web. The internet and the world wide web are 2 different things. This is further proof that the people who want this filter don’t actually understand the technology.

3. It will help protect children
In addition not blocking the main protocols over which child abuse material is distributed, the filter does not address other major forms of danger to children online: Online predators in chatrooms, cyber-bullying, etc.

Rant now continues:

As I’ve already stated, the blacklist is secret and unavailable under the freedom of information act. And the definition of the “other unwanted material” is hazy at best, including:

• Anything X-rated
• Anything R-rated and, in some cases, MA15+-rated, if it does not have a government-approved age verification page
• Anything that ACMA believe would be rated R, X or RC (refused classification), were it submitted to the OFLC

This is scary because people won’t know if something has been blocked or why. We could see the government blocking anything it doesn’t agree with, possibly including it’s competitors (unlikely, but possible under this plan).

Speed is another issue. In my opinion any delay created by a filter is unacceptable. Why? because a filter which introduces delay is only going to get worse as internet connection technology improves and will need to be upgraded. Many ISPs struggle to maintain quality connections when network utilisation is high without mandatory filtering.

Finally, peer-to-peer filtering. Stephen Conroy has stated that the technology to filter peer-to-peer communications exists and that they are testing this in the so-called “live trial”. Now deep-packet inspection tech does exist, but the processing power required simply to determine the type of a packet (used to throttle peer-to-peer) is already very high. To determine what specific data is being transmitted and then stopping that data being sent is even more difficult, maybe possible with a few megabytes per second and today’s equipment. ISPs today have to deal with gigabytes of peer-to-peer traffic every second. To filter this amount of traffic is, to put it simply, impossible. And there are legitimate uses for peer-to-peer as well. Blizzard pushes it’s patches out to customers via bittorrent, because they simply do not have the bandwidth to send (often 500MB+) patches out to 11 million people in a week. Steam (Valve’s electronic distribution software) uses a peer-to-peer distribution system for a similar reason. Simply put, peer-to-peer is the best way to put large files (eg. HD video) on the internet and its use is only going to increase so destroying its performance in Australia will be a sure-fire way to make sure we are stuck with 20th century internet in the 21st century.
