There is no anti-cheat, instead a global ban tracking system was put in place and server admins are now able to share the identities of players who have been caught cheating, banning them on every server, regardless of who is running them, by the hosts simply opting into the global ban system.
A global ban system without a more nuanced approach is a terrible idea. Operators of that global ban system will whitelist themselves, blacklist people they hate, and maybe even backdoor the mod that enables them to ban people in the first place. Server admins have no choice but to either opt into the entire system or have none at all, and both of these options suck. We’ve seen how this plays out already.
Score players by your own criteria, weight everything with different blacklists, greylists and whitelists, etc. and ban players if they exceed a threshold automatically. It won’t be perfect, but email catches most spam emails that way just fine.
