Simple AntiKillaura

A lightweight yet effective anti-cheat plugin designed to combat KillAura (auto-attack) and Hit Through Block (HTB) exploits on Minecraft servers running 1.20+ versions.

This plugin uses advanced timing analysis and ray-traced block detection to identify and prevent common cheating behaviors without false positives on slabs, stairs, or fences. It's configurable, easy to set up, and ideal for small to medium-sized servers looking for basic but reliable anti-cheat protection.
