Good application, good activity. When someone exploits, you must go into spectator mode, and observe if they are really visible or not. If they are completely invisible from all directions, then OM them to tell them to get out of the spot. If they do not move, slay them.
When someone mic spams, you tell them to stop spamming. If they do not discontinue, them gag/mute them for 5 minutes. However if they are spamming racist content, just gag/mute them without warning, and give them a warning for racism.
Other than that, application is detailed. Good luck!
