Can I come back to MetaFilter after I have been banned?
With a few exceptions, people who have been banned from MetaFilter may return under our Brand New Day policy. BND means that a user can sign up with a new account and mods will not "out" that user as being someone who held an account previously. This is a courtesy we extend to people who feel ready to change a problematic old persona, and it comes with certain expectations of good faith effort to change the old behavior. Users who open a new account and continue problematic behavior that caused their old account to be banned may lose the right to use that new account and/or set up new accounts.
