AntiExploitPreventer

Depends on: Protocolib 5.5.0 (dev)
This prevents against Opsec, but ExploitPreventer can't be blocked. I give up

Anti Opsec- & Exploit preventor plugin
AntiExploitPreventer plugin that deletes ExploitPreventer Players while bypassing Opsec and ExploitPreventer packet logger.

How it works
Due to a current ExploitPreventer client-side issue, sending packets with its nonce set to the ID of a previously sent packet causes the new packet to visually replace the original. The original packet is not deleted server-side, but it becomes hidden on the client.

AntiExploitPreventer exploits this behavior to allow "silent" ExploitPreventer and Opsec deletion:

1. When you delete a packet, the plugin sends a new message with placeholder text (like ** **) using the original packet's ID as the nonce.
2. This causes the new placeholder packet to visually replace the original in the client without triggering ExploitPreventer's / Opsec's fingerprint logger.
3. The placeholder packet is then deleted after a short delay.
4. By default, the plugin also deletes the original server-side packet to prevent it from reappearing after client reload.

This bypasses message loggers that track deletions, as the message appears to get replaced with placeholder text and then removed.

Also see CheatDetector that uses the same nonce exploit but to conveniently "silent" prevent a ExploitPreventer.
