we established that guaranteed anonymity is an important founding principle of PhysicsOverflow. The identity of users who want to stay anonymous must never be revealed by moderators.
But what about common users who deanonymize other users who want to stay anonymous? For example imagine the situation where two users have a strong diagreement and one of them "revenge-deanomynizes" the other by revealing his identity. Should such things be allowed or tolerated?
Or more generally, should anonymity not only be protected against deanonymization by moderators or other users with special tasks, but more generally against deanonymization by common users (who happen to know the identity of another user) too?
If guaranteed anonymity should hold in this more general sense too, how do we protect it if a user/moderator tries to violate this principle by deliberately and/or maliciously revealing the identity of somebody else?
Of course there is no way a user can find out the personal information of another user through PhysicsOverflow itself. The question is as to how we should treat a user who uses PhysicsOverflow as a de-anonymise another user from information gathered from elsewhere. Is simple deletion (of the comment) enough, or does any punitive action need to be taken?
An "anonymous user" is either a user who posts without logging in, or under a pseudonym without revealing their real name on the profile page in the "full name" or "About me" fields.
