Facebook Inc said on Thursday it took down posts and ads run by the re-election campaign of US President Donald Trump for violating its policy against organized hate.
The ads showed a red inverted triangle with text asking Facebook users to sign a petition against antifa, a loosely organized anti-fascist movement.
In a tweet on Thursday, the Anti-Defamation League's CEO, Jonathan Greenblatt, said: "The Nazis used red triangles to identify their political victims in concentration camps. Using it to attack political opponents is highly offensive."
The Facebook ads were run on pages belonging to Trump and Vice President Mike Pence, and also appeared in ads and organic posts on the "Team Trump" page.
"Our policy prohibits using a banned hate group's symbol to identify political prisoners without the context that condemns or discusses the symbol," said a Facebook company spokesperson.
"The inverted red triangle is a symbol used by Antifa, so it was included in an ad about Antifa," Tim Murtaugh, a spokesman for the Trump campaign, said in an email.
"We would note that Facebook still has an inverted red triangle emoji in use, which looks exactly the same, so it’s curious that they would target only this ad. The image is also not included in the Anti-Defamation League’s database of symbols of hate."T
The ads on the president’s page alone, which began running on Wednesday, gained as many as 950,000 impressions by Thursday morning. Identical ads on Pence’s page gained as many as 500,000 impressions.
