For the AC to be constantly maintained, it would indeed need a bigger team than the current SA-MP Dev team, depending on the members availability. We got very good coders in this community but I'm sure many or all of them got better things to do than keep SA-MP clean from hacks.
No team, no anticheat.
No anticheat, no fairplay.

Guess we will have to suffer with hackers when admins either are offline or don't do their job as they should, and those who use smart hacks which are a bit harder to identify through gameplay will take longer to be punished. It's a sad fact indeed, and our last hope is if ESL is actually adding SA-MP/GTASA to their Anti-Cheat program, although it's only for ESL SAMP purpose.
Else...nothing much will be available to do rather than script a good Pawn anticheat which won't solve all the cases but will solve some at least.
We've seen great and big plugins being brought to SA-MP. Examples of those are the Audio Plugin by incognito, object streamer, CNPC, etc... the anticheat plugin could just be one more of them and subscriptions for anticheat use could be implemented to keep their developer's team happy and motivated somehow.
