Some Facebook business Pages lost tens of thousands of fans today, but they shouldn’t fret. Facebook has confirmed with me that it’s currently purging fake accounts and Page Likes as it implements site integrity improvements announced last month. You can see the evidence on Pages like Zynga’s Texas HoldEm Poker whose fan count dropped by 96,000 today after steady after long steady growth.
Illegitimately created accounts are being deleted, and Likes gained from malware, compromised accounts, or deceived users are being removed. So no, everyone doesn’t just hate your Page’s last status update.
