I know FB scans private messages. You cannot send links with certain domains without getting an error message. Sure, they don't have some dude in a cubical looking at each and every message, but if they are scanning for domains, how hard is it to scan for keywords within those private messages? Mention your new iPhone in a message, and you see ads for iPhone cases. Make a Tony Romo joke and you see ads for an RGIII jersey, etc etc.
