... but in the presence of persistent harassment that will not cease online, tying the behavior to the person behind the behavior and bringing proper consequences to bear is the only regulatory system that actually works. There's a reason that you can be fined or imprisoned for trying to pull crap like that IRL.
But I am sorry that you were falsely accused. That is a possibility (both in doxxing attempts and in more "traditional" harassment).
False accusation is entirely possible, but it doesn't imply we just let harassers get on unchecked.
