Internet-based lobby group GetUp raised $30,000 in one day for their ‘Save The Net‘ campaign, which hopes to ‘plaster the internet’ with ads opposing the proposed net censorship scheme.

The campaign urged readers to donate in lots of $50 and $100.

“Your $50 will show 4000 people this ad, $100 will buy 10,000 views. Thanks for chipping in to defend our digital economy and democratic freedoms,” read the campaign.

By the end of the first 24 hours, the campaign had raised over $30,000.

GetUp is also hosting an online petition against the mandatory net filters. Over 75,000 ’signatures’ have been collected so far. Another 22,750 have been collected online by Taking It Global, run by Michael Meloni, the author of Somebody Think of the Children.

However, it is doubtful that these petitions could be formally presented to Senator Conroy in the Senate. The rules governing petitions (.doc) do not make allowances for electronic petitions. Instead, they state that “all signatures must be original signatures, not photocopies or faxed copies.”
