on social media, particularly on Facebook and Twitter. The QAnon conspiracy theory originated in the U.S. and alleges that Trump is fighting against a deep state cabal of "child sex-abusing" and "Satan-worshipping" Democrats. QAnon is a conspiracy with a massive following and has generated over 100 million comments and likes on Facebook in the year 2020 alone. The number of QAnon adherents is unclear, but the group maintains a large online following. Many have expressed the fear that QAnon's influence and its belief that Donald Trump will save the world make it support Trump's threats to prevent a peaceful transfer of power. Since the Associated Press declared Biden the winner of the 2020 presidential election, however, QAnon followers have experienced a crisis of faith or been in denial and believe that Trump is working behind the scenes to defeat the "shadowy forces" that determined Biden's win. Facebook has banned over 790 QAnon-related groups, 100 pages, and 1,500 advertisements in an attempt to dispel it. Instagram has also taken action by restricting over 10,000 accounts for which QAnon could affect population and the election. To avoid the creation of echo chambers and further political polarization, Facebook prevents QAnon groups from forming but allows individuals to post their support occasionally. Facebook has also prevented followers from organizing fundraisers and selling merchandise to raise money for the organization. After Trump lost the election to Biden, updates from Q declined dramatically, with the last post by Q made in December 2020. QAnon beliefs became a part of attempts to overturn the election and culminated in Trump supporters attacking the United States Capitol. That has led to a further crackdown on QAnon-related content on social media. The stolen election conspiracy theory claims that the 2020 United States presidential election was "stolen" from Donald Trump, who lost that election to Joe Biden. It justifies attempts to overturn the 2020 United States presidential election, including the 2021 storming of the United States Capitol. A particular variant of this theory is the "Soros stole the election" conspiracy theory that claims that George Soros stole the election from Trump. Polls conducted since the aftermath of the 2020 election have consistently shown that the majority of Republicans believe that the election was "stolen" from Trump.
