I've posted many times that I think FB is evil. Still do. And this may be the ultimate evil.
Facebook accounts cannot be deleted. With lots of diligence, you can figure our how to deactivate your account and that can be done. BUT, that in no way means your account has been deleted. Facebook is on the record (sorry I don't have a link) that accounts cannot be deleted and that Facebook retains rights to what ever you've posted.
See why I claim FB is evil?
It's like The Eagles sang in the song Hotel California:
Relax said the nightman
We are programed to recieve
You can check out any time you like
But you can never leave
Interesting, I never knew that. I wonder if the same thing goes for Twitter. I’m deactivating that one too.
