Thats true, but pm would help to report hackers way better. Say u see someone doing strange things, u can pm an admin to investigate this player without warning this player. Cause if u report in global chat, he will for sure stop hacking/glitching/whatever.
So besides an comfort option for us players it is an securety option for the server.
Beside of this, i agree with the removal plugin, its way more better then the current one.
