- How it works: Monitors player physics and camera offsets to ensure they aren't bypassing vanilla limits.
- Config files:
antifly.jsonandantifreecam.json📂 - Pro-Tip: ||If players with high ping are getting kicked, increase the "threshold" values in these configs to be more lenient.|| 🐎

- How it works: Hardens game logic against item duplication via menus, entities, or pistons.
- Config file:

Keep the server online and safe from malicious "crashers."
- How it works: Scrubs incoming packets for malicious payloads or data floods.
- Config file:
