Facebook took down the pages as part of efforts to remove violent social militias from its social networks, spokesman Andy Stone said.
Its dangerous organizations policy now includes groups that celebrate violent acts or suggest they will use weapons, even if they are not directly organizing violence.
Gibson, who espouses non-violence but is accused by anti-fascist groups of provoking confrontations, did not immediately respond to a request for comment.
Facebook last week removed content associated with the Kenosha Guard, a group which had posted a call to arms in Kenosha, Wisconsin.
