It appears to have been removed after one of Senator Anning's posts was reported for hate speech Supporters have shared their outrage at the page's removal, arguing Facebook picks on conservative commentators

The page and all its posts appeared to have been removed after one of Senator Anning's posts was reported for hate speech.

The comments in question, which were reported anonymously, were in reference to a speech he made in Parliament on the national Safe Schools program.

One person who reported the posts told the ABC they were similar to tweets the Senator has made where he calls Safe Schools a "degenerate program" for "commo perverts".

Senator Anning described the move by Facebook to unpublish his page as an attack on free speech.

"What we essentially have is a foreign corporation deciding what the Australian people can and cannot hear," he said in a statement, where he described himself as "the latest victim of the Zuck".

"The Australian public will not even be given the choice because Mark Zuckerberg has already made it for you."

The Senator wrote in his last post before the page was removed that Facebook was censoring conservative voices.

"We have seen the ongoing censorship of conservative political commentators like Avi [Yemini] and myself," it read.

The Senator was sharply criticised last month by fellow parliamentarians when he used the phrase "final solution" during his maiden speech while discussing Muslim immigration, a term associated with the Holocaust.

Supporters have taken to Facebook to share their outrage of the page's removal.

Commentator Avi Yemini, who is a member of the anti-Islamic party Australian Liberty Alliance and has also had his page removed for reported hate speech, said the ban was a sign of Facebook "meddling in Australian politics" and part of a wider "purge".

"They are picking only on conservatives," Mr Yemini said.

"I had almost 200,000 followers before Facebook deleted my page, only weeks before we launched my campaign for the [Victorian] state election."

Anti-Islamic group Reclaim Australia also criticised the move as political in a post.

"Anyone with a differing opinion is banned and silenced," the post read.

In a tweet, former race discrimination commissioner Tim Soutphommasane said: "Freedom of speech does not mean freedom from consequences".

A spokesperson for Facebook refused to be drawn on the reasons for removing Senator Anning's page.

They noted that Facebook's community standards stipulate that pages can be removed "because of multiple violations".
