This is currently not updated anymore. I thought I would just upload it here too. Might revisit it in the future though. I am thinking of returning at least long enough to finish the full release. It should support 1.8 - 1.19
1.18 might work fine. 1.19 wont
IP: test.flappyac.com - not online
MC Version: 1.17.1
AC Version: Latest dev build
This is currently mostly for testing the base I've made to make sure there are no bugs, once I've done that i will add more checks
Introduction
Flappy Anticheat is an anticheat I am making, it currently uses events but I'm going to use packets eventually. I will do my best to fix false positives and bypasses. I aim to make this anticheat highly customizable through the config so every message and check will be customizable.
This should work 1.8 - 1.17 but its only tested on 1.13/1.17
