An anonym is a signature that many people claim or may use without any single credential e.g. "we, trolls", which is not associated with a credential nor any particular pseudonym.

An anonym is deliberately subject to identity theft, that is, it is quite easy for anyone to use, and very difficult for anyone to say that whoever used it, "did not have the right" to use it.

They are accordingly a backbone of troll culture. One of the more amusing anonyms is the signature of the Troll Pope.
