This version of AntiCheat was inspired by Mineplex's MAC (Before it became NCP). When a player is using hacks, instead of stopping it and giving players no visible evidence to record, it allows hacks and notifies staff that a player is hacking. If the hack is severe enough, the player will be kicked.

Flight

iAntiCheat has 4 different levels of severity when flying. The longer the player has been in the air, the more severe. Staff will be messaged when a player has been in the air for certain increments of move ticks. Once the player has reached an extreme amount of flight, they will be kicked. I've worked as hard as I can to eliminate false positives, but they still happen. Don't swing the ban hammer too early, and I suggest spectating a player before punishing them anyway. Velocities shouldn't create false positives either. For example, if you have a plugin that sends a player flying when they step on a pressure plate, they will be ignored for a few seconds. I should also note that if you are spammed by the same message that a player is flying, it's a small bug and doesn't mean that they're hacking at a more extreme level.

Speed

Speed is detected at moderate levels. Just a note, potions and other speed modifiers may cause false positives. In rare cases, some plugins may also cause false positives (Ex: Somehow making a player sneak and sprint at the same time) Most of these issues will be addressed in a future update.

Phase

Phasing through blocks is now detected. They will be instantly kicked once a player moves into a solid block.

Compatibility

This plugin runs on 1.7-1.8 servers running Java 7 or later.
