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.
