Facebook Thursday removed one of the largest groups linked to conspiracy thinkers who call themselves QAnon. The group, called Official Q / Qanon, had nearly 200,000 members and violated Facebook's content policy multiple times.

Facebook removed the entire group after the platform had to take action several times against individual messages in the group. These posts were removed for bullying and harassment, hate speech and false information that could lead to harm, a Facebook spokesperson told Reuters news agency .

QAnon is an umbrella name for multiple theories about different people and events surrounding American politics, all of which would ultimately be interrelated. It has its origins in the controversial forum 4chan and from there spread to include 8chan and common social media such as Facebook, Twitter and Reddit.

In May, Facebook removed a network of QAnon accounts guilty of "coordinated misleading behavior" leading up to the US presidential election. Twitter went on last month and said it would delete or limit many thousands of QAnon accounts.
