Corinthian and DB were two different people. DB was a relatively decent sort of a mainstream troll until he started to copy the behavior of Corinthian. But yes, you are right - this forum continues to see many times banned member(s) re-appear and continue their same old pattern of multiple IDs and misbehavior. When they do, unapologetic and without repentance or agreement to follow the rules, I'll always be here to be their huckleberry.
People (a very small number) can debate that til they are blue in the face, but it will change nothing.
