Since Facebook’s algorithms place a high value on popularity (as measured by likes and shares), these highly liked and shared pages therefore have a much higher chance of appearing in people’s “Feeds” and being seen by other Facebook users. Then, once the page has a sufficiently high popularity rating, the like-farmer either removes the page’s original content and replaces it with something else (usually malware or scam advertising); leaves the page as is and uses it as a platform for continued like-farming in order to spread malware, collect people’s marketing information or engage in other harmful activities; or outright sells the highly liked site to cybercriminals in a black market web forum.
