Not many people know how easy it actually is to get scammed on Facebook. It happens every day, possibly to you.

Here are four of the most-common scams:

Like farming: this is the one where you see the photo of a sick kid in the hospital holding up a sign that says "If I get a million Likes, I might get a new liver!" or something like that. It's called Like farming. When you Like a post, Facebook puts a copy of that post on all your friends' news feeds. After 100,000 Likes, the page owner puts up ads, which then show up in all of your news feeds.

Celebrity sex tapes: clicking on a link that promises a new celebrity sex tape takes you to a site where you fill out a survey, but never actually see the alleged tape. Meanwhile, the website is making nasty posts in your name on all your friends' timelines. More likely than not, it is also loading malware onto your computer, stealing your personal data or spying on you with your own webcam.

Who viewed my profile: there is no legitimate way to check who views your page. Facebook does not release that information to anyone. After clicking the link, you are prompted to install a new web-browser extension, and those can record everything you enter on other sites, or even take over your entire profile.

Change your profile colors: this advertises an app that will allow you to change your profile to a different color, but instead, it takes you to another website where you are asked to fill out a short survey. The information you give is sold to marketing companies who then fill the Internet with more spam.
