Sorry for the necro-post.
First I want to say that yes I can see this being annoying. I would find it annoying if I wasn't apart of it myself.
The only thing that bugged me was the lack of warnings. I wasn't ever asked to stop - suddenly banned. And Canary using pink chat once in the "10 (
) maps" while another admin was there already doesn't count - considering we banned on the spot - with no prior warning as I said. A kick from server or pink warning could've sufficed. Is it not an admins job to enforce the following of the rules & not just persecute the rule benders?
