Facebook and Instagram Ban the Proud Boys and Gavin Mcinnes Occurred on 20 Oct 2018

A Facebook spokesperson confirmed that both Facebook and Instagram banned The Proud Boys and several accounts linked to the organization including its founder, Gavin McInnes.

In a statement, Facebook told TheWrap:

We will continue to review content, Pages, and people that violate our policies, take action against hate speech and hate organizations to help keep our community safe.

As Breitbart pointed out, these bans happened a week before the November 2018 midterm elections.
