representative sample. Some customers complained about over-blocking, and withdrew from the trial. One example was the censorship of the pornography website RedTube: ACMA refused to confirm or deny if the site was on the list, or if the site was legal. Leading Australian statistic experts, however, have labelled the trials as unscientific, lacking in proper methodology, unrepresentative and "about the worst way you can do it". In December 2009, the results of the filtering trial were released. Stephen Conroy stated, "The report into the pilot trial of ISP-level filtering demonstrates that censoring RC-rated material can be done with 100 percent accuracy and negligible impact on Internet speed". However, concerns have been raised about the report: only a small minority of ISP users participated; the trial did not test using any high-speed Internet connections similar to those available with the National Broadband Network; there is evidence that the filter was evaded; and with only 600 to 700 sites on the RC blocklists, the effect of the filter would be marginal at best. Opinion polling In February 2010, ABC's Hungry Beast program commissioned McNair Ingenuity Research to perform a telephone poll of 1,000 Australians. Key results were To the proposition "We need Government regulation of content on the Internet the same as we have Government regulation of content for other media" 62% agreed, 35% disagreed. "Having a mandatory Government Internet filter that would automatically censor all access in Australia, to overseas websites containing material that is Refused Classification?" Refused Classification was defined as "Images and information about one or more of the following: child sexual abuse, bestiality, sexual violence, gratuitous, exploitative or offensive sexual fetishes, detailed instructions on or promotion of crime, violence or use of illegal drugs". 80% were in favour, 19% against. "A Government appointed body determining whether a website is appropriate for you to visit?" 50% in favour, 46% against. "If a mandatory Internet Filter is established, are you in favour or not in favour of the community being advised which websites have been Refused Classification and the reason why they have been refused classification?" 91% in favour, 8% against. "Some opponents of the Government's mandatory Internet Filter are concerned that if it were put in place, future Governments could use Internet Filtering technology to restrict free speech or censor other forms of website content they don't approve of. Do you share this concern?" 70% concerned, 27% unconcerned. The
