A German teen learned her lesson after forgetting to set her Facebook to "private" around the time she had posted a party invite to her sweet 16. As a result, 1,600 guests turned up (as well as, 100 cops) causing her to flee the scene. She had meant to invite only a handful.
Don't use Facebook so much that you forget to interact with humans
According to a study, social networking sites like Facebook could raise risk of serious health problems. In reducing face-to-face contact with humans - emailing people instead of seeing them, for instance - could affect you in ways you never knew, reports The Daily Mail.

Don't be on Facebook if you're running from the law
We realize this tip is a controversial one, but that doesn't make it any less true. Word is, courts are using the social network to go after individuals who are otherwise unavailable. "In March, we reported on a lawyer who surprisingly used Facebook to contact a debtor and try to get them to appear in court," according to Scribbal.com. Doing so helps cases move along when people needed by the court system are not reachable via other means.
At the moment, New Zealand, Canada and the U.K. have adopted the process, but Bloomberg says the U.S. might be next in line to try similar practices.
Don't get a fake Facebook girlfriend because it's just lame
Uhhh, people can tell if you're using a service like Cloud Girlfriend or literally asking someone to be your faux significant other on Facebook. When your friends realize they've never met your woman, it'll only draw flags. Even worse, you'll be violating Facebook's Terms of Service agreement. Although we don't know what the consequences are like for not following Facebook's rules, isn't public embarrassment enough?
