This is a tiny portion of the actual problem here, which I have been exploring and speaking about since its inception.

“Avoid the urge to like, share, or comment on anything that begs or challenges you to do so.

If you’re not paying for a service, then you’re not the customer, you’re the product. That’s the case on Facebook. Your likes, shares, and comments are the commodity that is sought after to increase the popularity rating of nefarious pages. Your personal information and friend network are sought after by scammers and the like.

“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.” (1)”
