I reported it instantaneously to Matthew and FireZ. I think I advised people on the thread in the donator lounge not to abuse it also. I had the donor rank for like 30 mins if even that. I can't remember if I left it on for fun or because I just hadn't bothered to change it back. The difference between mine and x339's circumstances are I had the rank for 30 mins, reported it to 2 admins, and changed it back. He had $200 donor, along with a user image for a whole week, and it doesn't sound like he did anything to have it removed or even report the bug. It's true that Syed had the rank too, but it was the same circumstance as mine, he only had it for 30 mins before Corey asked us both to revert it. I found it a bit annoying I was going to be banned for the same timeframe as him, when the circumstances were quite different.
I've no idea who unbanned us, either way I'd like to say thanks very much.
