You may have seen your friends liking this link. DON’T CLICK ON IT.
It will have been accompanied by the image of a lady’s posterior. Naturally you’re supposed to click on it like a moron. This is a standard type of ‘Like-Jacking’ spam. Once you click on the link and visit the page, a script automatically makes you like the page too, which then advertises the fact on Facebook. As a result, more people click on it, and unwittingly like it, and so it spreads.
Lesson here: Don’t click links just because it has a stupid headline and a tempting image. Be smarter.
