Daniel Walker poses at a rally. ‘‘they [sic] completely twisted our video around to make it look as thou [sic] we have threatened campbell newman,’’ his message says. ‘‘they completely went against what we were trying to portray in the video... but bad publicity is better then no publicity. at least people are showing concern with the new legislations.’’ Mr Walker has previously campaigned for the rights of single parents with RiSE Queensland founder Bronwyn Rees at Reddacliff Place in Brisbane’s CBD. Although Ms Rees admitted she has never seen the man she knows as Daniel without a Guy Fawkes mask - the symbol of the Anonymous movement - she said he was a ‘‘good man’’.

They are for freedom of speech. They are not threatening.’’ Daniel Walker marches in Brisbane's CBD. A photograph on his Facebook page also shows Mr Walker marching with the Queensland Socialist Alliance along Adelaide Street in a protest against the multinational producer of genetically modified food Monsanto.

Fairfax Media has asked Mr Walker for comment. He is yet to respond. In a message on YouTube, the clip’s creator - believed to be Mr Walker - said the final line of the video was not a veiled threat to the Premier, but rather a twist on Anonymous’ famous sign off: “We do not forgive. We do not forget. Expect us.” ‘‘ ... they used our motto "expect us" and turned it into a threat ... ok, so what did i [sic] threaten to do? lol,’’ Trojan Walker’s response reads. ‘‘i [sic] have never hurt anyone nor has anyone i [sic] associate with, but, we are watching, and he can expect his lies to be made public.’’

However, Police Minister Jack Dempsey said the creators of the clip were ‘‘gutless cowards’’. ‘‘They have to hide behind a mask,’’ he told reporters on Monday. The anti-government YouTube clip features an activist speaking in a computerised voice. ‘‘There are cases where normal people on motorbikes have been harassed, searched and investigated for nothing more than riding a motorcycle,’’ the message says. ‘‘The bill has already been used against everyday people like you and me ... Campbell Newman has gone too far.’’

The footage used appears identical to that used in other YouTube videos posted by Anonymous activists in the US. Police are investigating. Loading Anonymous, a loosely associated international network of activists and hackers, is known for highly publicised cyber-attacks around the world since it was established in 2003. In 2012, Time magazine called Anonymous one of the "100 most influential people" in the world.
