fight against terror. A hybrid filtering scheme was rated the best, but it is ineffective against dynamic content such as chat pages and instant messaging, and had political implications because it required the existence of a blocklist of censored pages. The report instead advocates the use of takedown notices for extremist content, and prosecutions to "signal that individuals engaged in online extremism are not beyond the law". The Metaverse Journal suggests that because web filtering logs every site visit, and some information about who is visiting the site, then it is ripe for abuse by whoever runs the filters. It potentially allows surveillance of any user of the Internet, such as journalists, political opponents, or even the family members of politicians. Ross Fitzgerald of The Australian believes that the filter was not introduced in 2010 to defuse it as an election issue, and that if it is re-introduced into the next parliament it could be even more censorious than the current proposal. Australian radio presenter and writer Helen Razer dislikes the filter because she enjoys pornography, does not believe it causes harm to adults, and doesn't think that children are at much risk: "I enjoy pornography. Perhaps not quite so much as I enjoy living among citizens who take an entitlement to free speech for granted. But I do like it quite a lot. And it seems that my porn is endangered. If Conroy's clean feed works, which some tech sceptics argue that it cannot, it will prevent access to all pornography ... I can report that one doesn't simply amble into X-rated or even R18+ material ... I have become adept at this; children, presumably, have not. And if they have, clearly they are the issue of the world's most reprehensible parents and should be sent to live with Hetty Johnston forthwith ... Despite the best efforts of some, there is no evidence that pornography will negatively affect me or other consenting adults ... The only lasting effect of my access to porn is a reflex giggle when the pizza delivery man knocks on my door." Attacks on government websites On 26 March 2009, the Australian Classification Board’s website, http://www.classification.gov.au/, was attacked by the Internet group Anonymous, automatically redirecting visitors to a page on the same site with a message mocking censorship efforts with the text: This site contains information about the boards that have the right to CONTROL
