"Zero notice" seems to be a common thing at Facebook. Same happened with my personal account, just gone one day.
To be fair, I guess it was because I didn't have my real name on it but it was the name my blog readers know me by. Several thousands of friends - gone, without a warning.
I currently have about 15 different Facebook accounts, each under false names. So far none of them have been shut down, or even questioned. Maybe it was because you got to such a high amount of friends that they took notice, mine are rather low, around 50 - 100 friends on each account...
Probably. Or your 'false names' are not as 'flashy' as mine! I still thought it was quite harsh to just delete the account without any warning or notice at all.
And I've got a lot of friends who aren't using their real names either and are getting away with it, no idea how they are tracking you down.
Insisting on real names is a big part of what makes Facebook so uncool and corporate to me. I want the Myspace days back, seriously. They didn't care at all.
A lot of people on my list have completely preposterous names that are clearly not real. I've changed mine many times to many stupid things and never had a problem.
That depends on if you consider the point of facebook to give detailed, accurate biographical data about yourself away to a company with which you have no monetary relationship, so that this company can then sell it, or not.
