Thanks for taking the time to explain it to me without calling me a dipshit, I thought PAM already did the checksum bit (which is a tool for checking random file alterations not manmade file alterations, two different files can easily have the same checksum). We are forced to stream to PBBans because of CB but there's nothing you can do about that. As for the other ppl that use our server, well we're a pretty close group everyone trusts each other and I'm sure that no-one cheats. I'm not the only admin, everyone who helps with the bill gets rcon access and if they want they can edit the files aswell (though there's only two of us that can at the moment).
I'm against hacks aswell but I'm not convinced its such a big problem. I've played against 2 or 3 people who were cheating over the course of at least 3 years. If they're cheating I can easily look it up in the pbscreens on the server and if its not our server I can just go to another.
Actually I did feel like I was being accused of being a cheat, not by you though
I figured the only reason why PBBans exists is because of cheaters (I can't think of anything else).
