As Rootil mentioned, there are tests ongoing regarding catching cheaters and effectively enforcing bans. The only problem here is the distribution of a client. Imo it doesn't make much sense to split such a small player base by hosting anti cheat enabled servers where only player with that client could join.
If we could distribute the client with a force update to the nexus hook the problem could be solved within days.
I proposed nF to check the source himself or even manually compile when we are ready.
