Is this the 100th thread about this very topic? If you are going to post something about mods/hackers/spammers, just post it in the same topic (if its still open). You may even find answers to your question.
We are currently trying out a NoCheat + (plus) which is far more better than Anti-Cheat. This will most likely be replacing Anti-Cheat, but for now please PLEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEASE stop complaining, we are fully aware of the matter.
We know that there are hackers/spammers on almost all 56 servers, but it is almost impossible to have a mod on all these servers 24/7, we also have lives outside the internet.
Just keep reporting, this also reduces the amounts of hackers/spammers (that's when there is enough evidence).
