Hi GMs,
Shotbot is one of the best players on the Asmodian faction; not only that, but he is also one of the friendliest, and quite frankly he's funny & fun to play with.
If he got banned for a sarcastic comment that any reasonable person would have interpreted as a joke (we sure all did, when we were with him), not as an actual breach of ToS by selling accounts / RMT, etc, I believe that requires an immediate re-consideration and undoing of his permanent ban. It's simply not reasonable, and not even the appropriate "punishment" for the "crime". Sarcastic comments happen all the time, and blankly taking them at face value is unreasonable.
Furthermore, I believe you're focusing your banning/curating efforts on the wrong types of "offenses".
