Spammy messages and / or posts from friends? Facebook has it all. Most of the time you’ll receive such posts / messages by friends whose accounts got hacked. Often, when you click on the links you see in those posts, you’ll get hacked yourself.

Be careful what you click on – that goes not only for Facebook, by the way. If you hear from a friend you haven’t heard from in some time or if a friend tries to make sure you click on some link that to you sounds fishy: don’t. Contact your friend via other means than social media to make sure it’s really him.
