Errrm still feel you over reacted, its not a abuse of power to ask why you did something, its not like they removed the ban, nor did they tell you to remove it, they were asking why. I would do the same if a user joined complaining they were banned, I would join and ask the room owner what was going on so I could resolve the matter in help desk with the user complaining. you in you non your biz reply left it that they didn't know what was going on so no notes to pass on to the other staff so you ended up getting bugged about it more when the user complained again. simply telling the staff members what was going on could of saved a lot of headachs, for you and the staff.
my answer to you is you talks shit and maybe you is on sparkpea staff. if you had a room and someone came in your room and f ed about with your room and you banned then would you like that someone to go to the helpdesk and ask the sysops, guides to come in your room and ask you why they are banned. what i reads it that everyone who is banned from a sparkpea chatroom can run to the helpdesk and ask why ? and that goes for all room in sparkpea or any other chat network
