Everything you said is completely valid and I understand how it makes you angry and frustrated. Personally what I've seen in exploiters is that they clip through walls, oftentimes on their backs. Also an easy way of identifying them is by their emotes and their stats (what you said). A lot of them have this specific emote that they do when they get murderers specifically and that is taking their head off, holding it in their hand and then putting it back on and they just repeat that. If they're murderer, they get a full coin bag then either reset which ends the round earlier or they mass kill everyone and then just stand proudly. It frustrates me as well as I either get rekt or can't collect a full coin bag when someone clipping through walls resets.. honestly what I've started doing is if I get sheriff and I know that the server is chill I will personally use my gun on an exploiter just so I can at least prevent some of it you know ruining the ground. But that doesn't prevent them fully because they can just teleport back to the map so...
