About 175,000 accounts followed one or more of the fake UK pages. Roughly 4,500 accounts followed one or more of the fake Instagram accounts. Some of the removed pages included "Anti far right extremists," "atheist research centre" and "halel speech." 

The Atlantic Council's Digital Research Forensic Lab, which studied the network of fake UK accounts, found that the accounts "seemed designed to amplify pro-Islam and anti-extremist messaging, including by engaging with anti-Islam commentators."
