I heard that the chest per chunk limit wasn't working on the server and thought that would be a good practice plugin to make.

This plugin can also limit any other type of block to whatever limit you want to set. SaberSupe/BlockLimiter: Spigot plugin to put a limit on number of a block in a chunk (github.com)
