Well, if Kye didn't remove aru's/peter's AC back in ages(that brilliant code still does exist tho), we would never face these kind of problems, afaik back in 08/09 when it got released, for like 5 months SA:MP was running almost out of cheaters and it was astonishing, many of them literally gave up. But, since the leader of samp dev team decided to screw it up himself, there's pretty much nothing we can do about it these days, since the AC would have to be re-released together with SA:MP.
I'd say, just promote more lads, the active ones, so you get 1 admin ig in every timezone who can monitor the game. You have to show them some trust and they'll eventually work hard for tha payback!
