I personally have not had any issues with Toly. I would say if he could tone-down/completely remove the hostility he could come back. I have read the threads/messages he has sent but everyone has a different personality.

Me personally, he did help me quite a bit with killing stuff/he did help others. He isn't the worst person to ever play Annihilus. I believe I take that role, as worst person to play. Haha
