killing an admin is banworthy on community servers!

Was playing on a German community server because I've also mostly been sticking to official ones. This one was Ballerbude, where I spotted and killed "Fix", who I can only assume was an admin, and was banned for it. My mate in game asked why I was banned, and they said I was using ESP...yeah fuck community servers. (sped up the boring parts where I was reloading etc) just wtf.
