I am not sure about your experience with Anti-Cheat of Jartex, but it detects and punishes players very efficiently. You can look in
https://jartexnetwork.com/bans/ and find that majority of the punished players are cheaters.
In the future if you need immediate help or can't record rule breakers, do /staff ingame. This shows the online staff at the time, their Status and which server they are in. You can invite them
to the party in Minigames and private message them in other servers.
In my opinion, the Anti-cheat works fine.
