I suggest a pvp mod. A staff position that is well informed about hacked clients and glitches and stuff. Just a suggestion, it would keep the regular staff doing their regular jobs, and the pvp mod watching over the pvpers. Nick has suggested it before, he's the one who brought me to the idea of posting this suggestion. Sorry it's not worded perfectly, but you get the point.
This is kind of what staff are for. I mean, we dont get thousands of hackers, and if staff see someone hacking, they ban them, and if players see a hacker, they will report them
