facebook: is it possible to block someone who's not on your friend list?

[Angela]

As in someone you purposely aren't facebook friends with looks you up on google, comes to your limited fb profile, and sends you a message. Is it possible to block such non-friends from messaging you?

[Sophia Jungenberg]

Yes just click on the person, click options, and click block.
You can block anyone you want. It's your Fb!

You can set your settings so that your Inbox receives messages from only your friends.

In the Other box, I think you can still see some from non-friends.

This is why Facebook sucks. They're all about making money and they don't give a crap about its users.
