EnfIllegalJoin is a lightweight and configurable security plugin that allows server administrators to block players from joining the server using specific Minecraft clients or modifications.
The plugin is designed to help protect your server against:
- Unwanted modded clients (e.g. Forge)
- Data-stealing tools (e.g. World Downloader)
- Cheating or unfair gameplay advantages
- Clients that violate your server rules
When a player attempts to join using a blocked client, the plugin can:
- Instantly kick the player
- Display a custom kick message
- Execute console commands (e.g. logging, banning, alerts)
