If we're ignoring the fact this was closed, @ThePenguin...
I see no way you weren't trying to provoke a response from them. I understand it was a joke. But removing a whole channel's admins/mod/ect of people you (I assume) are not friends with is just irritating them. The channel (or sub-channel) owner is the one who has the final say in such things.
TLDR: Don't be a dick. If you're going to be, at least be friends with the person first. Otherwise it's basically just imstigating with people you don't know that well. Don't do this again.
