I'd say that happens a lot _less_ on facebook though compared to a site like reddit, because more people are cognizant that they're using their real life identity. People also post pictures of their shiny new credit cards to twitter, it's not because they don't care about fraud, they're just not aware of how twitter works. Some small portion of people really don't care and will gladly threaten to rape you under their real name, but I'm guessing that the majority of the ones you see are people who just aren't very internet saavy.
