A group of anti-filtering activists are trying to test the Australian Communications and Media Authority's (ACMA) ability to censor the Internet.

Recently the ACMA added an anti-abortion site to its blacklist (in existence since 2000) that contained images of aborted foetuses. Under the authority's guidelines, a page that links to prohibited content is also considered prohibited.

To test boundaries of this legal minefield the activists posted a link to the "prohibited" content on the broadband user group website Whirlpool.net.au.

Whirpool's host Bulletproof Networks was then served with a "Link Deletion Notice" and threatened with an $11,000 fine if the link was not removed within 24 hours.

In a further test of the ACMA's resolve and potential hypocrisy, the Activists have placed the offending on the ACMA's own Wikipedia entry under the title of Internet Censorship and Criticism.

"It can't issue a removal order to Whirlpool for linking to an anti-abortion site, but not take equivalent action against Wikipedia," the activist told iTnews.

"If ACMA blacklists their own Wikipedia page, well that says it all doesn't it? If they don't, that is a very, very strong reason to call them hypocrites for making vastly different responses to two sites linking to the very same material."
