I understand you, it's annoying and I actually would like an Anticheat improvement too but don't forget that making a really good anticheat is very hard. Moreover, Jartex is a cracked server, so there are more than a premium one. Then, everyone's lag complicates the actual cheat detection and it's not always the server: false kicked people for using Client Modifications are often due to player's lag. Therefore, to finish with, if you want an Anticheat improvement, so make that people don't lag.
I hope you understood me.
