EnderChestGuard is a Paper plugin that protects players' Ender Chests from being stolen. When a player places an Ender Chest, the plugin saves their UUID and the chest's location. If another player tries to break that chest, they receive a warning. After 3 violations they are permanently banned. Ender Chests with no tracked owner (placed before the plugin was installed, via /setblock, etc.) can be broken by anyone freely.
You can change the number of allowed strikes, warning messages and if the enderchest should be dropped on violation in the config.
commands:
ecg info <player>
Shows the number of violations.
ecg resest <player>
Resets the number of violations of a player to 0.
ecg avoid <player> <time>
Allows a Player to break any enderchest in a certaint time range.
This plugin only exists because my friends kept stealing my enderchests. But because I'm to stupid to code, this is unfortunatly made with claude.

Banns people if they steal enderchests.
