I posted earlier how Facebook would begin cracking down on fake Likes on their service. Somehow I missed this story on Business Insider that explains how Facebook is going about this.
This is worth a read, and as I pointed out earlier, the fact that Facebook has announced this effort is a tacit admission that Facebook hacking is possible.
Facebook announced that it will be making a concerted effort to crack down on removing Likes on brand Pages “that may have been gained by means that violate our Facebook Terms.”
Although a source familiar with Facebook told Business Insider that engineers have already begun the suspicious Like invalidation process, brand pages can expect to see an average decrease of approximately 1 percent of Likes accumulated by malware, compromised accounts, deceived users, or purchased bulk Likes.
