A technology whitepaper by ISP Watchdog, which specialises in supplying filtered internet access, is pointing to several problems with official Net censorship trials in Australia and New Zealand.
The whitepaper was published on whistleblower site Wikileaks and contains Watchdog’s recommendations for managing URL (Uniform Resource Locator) lists to block sites containing images of child sexual abuse.
Among the issues that affected the Australian Communications and Media Authority (ACMA) trial were URLs with question marks or ones that were longer than 200 characters. The first problem blocked all YouTube URLs in the ACMA trial.
The question mark problem was solved with a firmware upgrade, the document says, and the long URLs one with a redirect to shorter links.
