What are some negative statistics about facebook?

[Chris]

With the recent changes they made this year to facebook, any message you leave someone else will be visible on the homepage of all your friends. Same goes for pictures, groups joined, relationship status changes, and general status changes.

Now those features can be turned off but many won't realize or won't know how to turn them off until they say something that everyone they know shouldn't or wouldn't want to see.

Also, there have been reports of employers and teachers at more conservative schools looking on facebook and finding incriminating photos of people smoking pot, drinking underage, etc and have then either fired, suspended or in one or two cases expelled the student. Nowadays it can be the easiest background check for an employer to perform when someone applies.
