A small, but good-looking plugin made by me. Although arguments here are a bit scuffed as they're only limited to 2, 1 for the player and 1 for the reason, I just wanted to document my progress the only way I knew how. Spigot.

This being said - feel free to leave feedback!

Commands
/blacklist (or /bl) <player> <reason>

Features
Config file, for basically everything you would want to change! (except maybe the initial ban screen, as of right now)
Embedded into Minecraft's vanilla ban system, use /pardon to unblacklist players from banned_players.json.
