Bukkit

Compatible with PaperMC & Spigot, and anything else that supports Spigot API.

HideStream is doing one simple task for you; hiding spam output such as join & leave messages from appearing in the chat. This can be beneficial for high-traffic servers, where players are logging out and in repetitively.
You can also adapt HideStream to suit your server perfectly using a configuration file provided.
