A local man said his Facebook account was hacked and the hackers posted hard-core porn to his account.

Others on Facebook responded saying it had happened to them too, or knew people it had happened to.

Rather than someone "hacking Facebook" a couple people believe it's the fault of those "apps" that ask you to give them access to your Facebook.

So if someone you know posts a picture or video to Facebook that is incredibly inappropriate and uncharacteristic of them, remember it may not really be them!
