Facebook doesn't even begin to check identities - real or false. I signed up under a pseudonym some weeks ago, with a real mail address (I own my own web domain so I can create up to 500 email addresses) and inserted a false name and age. I looked at the site activity for a few days, just to see what it was all about and how it worked, and then stopped my account. My opinion was (and is) that Facebook is a waste of space.

Absolutely no check on me whatsoever, by the way. Today I logged on to the pseudonymous account as if nothing had happened - and got an email which said:

Hey ----,

The Facebook account associated with -------@----.net was recently reactivated.

If you were not the one who reactivated this account, please visit our Help Center (http://www.facebook.com/help.php?page=420).

Thanks,
The Facebook Team

Obviously a computer-generated message to my pseudonymous email address. The potential for doing all sorts of anti-social things on Facebook is huge, as some 'Catters have found to their cost, and I shall avoid it like the plague in future.

But, even having ceased the account, it will apparently still lie there... fallow...
