What are the signs that a facebook profile has been deactivated?

[Bob]

When you try to login to your account and it says wrong password or this username doesn't exist, it's a pretty good sign that the account is deactivated. Maybe your friends have decided they need lives and stopped wasting their time online and are currently burning the thousands of calories they accumulated while sending flairs and poking you. Instead of vandalising your facebook wall they may finally resort to good ol' fashioned spray painting walls like the old gangsta days
