Facebook says it will move to ban groups that openly support QAnon, an unfounded conspiracy theory relating to the existence of a supposed child-trafficking ring run by celebrities and government officials that can only be stopped by US president Donald Trump.

The ban will extend across both Facebook and Instagram with all Facebook pages and groups and Instagram accounts spreading QAnon-supportive content to be removed, regardless of whether they encourage violence.

Facebook said it will consider a variety of factors when identifying banned content including the bio and ‘about’ section of a page, as well as any discussions within the page.
