An anonymous in-house chatroom at Facebook that had become a “hub” for Donald Trump supporters was closed last year by the company after comments made on the forum disturbed management, according to several reports. The forum, called FB Anon, was shut down last December. Debate usually centered around conservative issues, but sometimes deteriorated into racist and sexist statements. The group had hundreds of members, and content posted there was talked about throughout the company, reports Business Insider.

The forum was built in May 2015 as a place for employees to vent their frustrations and share sensitive information, away from managers. It gradually became a center for backers of Donald Trump as the election drew nearer, with many right-leaning workers using the forum and considering it a safe haven for their views. “There was a feeling that everyone at the company was a Democrat or left-leaning,” one former employee told Business Insider.
