a privacy question about facebook

[BWMWAP]

Ok, so I don't claim to spend much time on Facebook, but from what I can make out if you go to the top of your profile there's a settings link. Click on that and one of the options is "Privacy Settings". Under that you'll be able to get to profile controls which gives you the "world controls" pieces.

There's also a "Block People" option on that page.

Good luck!
