Also counterintuitively: unlike real names, stable pseudonyms *more identifying* and a more limited resource. There's plenty of people with a display name of "David Thiel" backed by an email, but if I act like a prick and lose my unique id, I can't just swap to a new one without a loss.
every single study done on this shows that the actual best behavior is done under consistent pseudonyms and people behave worse under real names it’s counterintuitive but at this point the real names thing is willful denial of evidence
