Some people found it funny. I don't really care; I just wished she at least had the goddamn decency to send me a note saying she thought the pose was sexual comedy gold. We probably wouldn't be having this conversation were that the case.
Alright, what you should have done first is Noted a moderator or administrator to have that thread locked. You also should have just dropped the issue altogether, waited a few days, and come back when the ill-temper had died down. Threads like this only add fuel to the fire and give people more ammunition to attack you with.
As is often said, don't feed the trolls; that means they win. I would suggest having this thread locked as well when you make that other lock request.
