Yes, tye has come forward now, after I wouldn't let it die.
I quote myself:
I still intended to identify myself when it seemed appropriate. I had started that process in private messages before you posted this.
It is not true that I came forward because you wouldn't let it die. You said "after" but I still read that as "because" (it doesn't make sense to say "after something didn't happen" and mean "after in time but not as a result of", that I can tell).
If there is an abuse, there is a system for responding to it (one part of which is posting just like you did). A guarantee that the silenced one will immediately know who the culprit was is not part of that system. I think it would be a mistake to make that a part of the system.
