Many of the accounts affected by Thursday’s announcement had already been banned from other social media sites. For instance, pages relating to Infowars were removed from Facebook but until now the conspiracist news site had been allowed to maintain an account on sister service Instagram.

Yiannopoulos, a former Breitbart News employee, had already been banned by Twitter and Facebook but the decision to remove his Instagram account means his only mainstream social media outlet will now be on YouTube.

The change in attitudes suggests Facebook is adopting a more consistent approach across all its platforms. The company has recently specifically banned white supremacist material from its service and has come under increased pressure to act against such content following the Christchurch terror attack, which was livestreamed on its network.
