A anti-attack and anti-spam plugin

Note: Since only BukkitAPI is used, it is not possible to achieve perfect defense, but the server version can be 1.5 or even the latest version.

Introduce

This project was previously written, was used for low version of the bot attack defense, but because our 1.5.2 Minecraft server is not open, and then only a few small updates.

Dependencies

• KotlinMC

Feature

Can be used for defense:

• Fast/slow/bypass bot attacks (single ip)
• Distributed bot attacks
• Motd attack
• Play normally while being attacked
• Spam
