Have you ever searched Facebook for someone you dated like fifteen years ago -- partially out of boredom, partially to see who aged better, you or him? (OMG, is that a bald spot? You win, girlfriend.) Some people call it Facebook stalking, but that's just a rude term for a perfectly normal activity. Humans are naturally curious, after all. So you searched an ex-lover on Facebook, who cares?
Well, I'm not saying anyone should care, but just as a possibly useful FYI, Facebook archives those searches of yours. As in, every single thing you search for, whether that's "David Smith" or "Tijuana donkey porn," is forever saved in your Facebook profile. Which might be awkward if someone else were to stumble upon it, you know what I mean?
I'm sure your search history is totally FINE. But juuuuust in case, here's how to clear the whole thing out.
