This is a proof of concept, that Kotlin mods are possible in Minecraft 1.7.10.
Do not use this version for production tho. Use BanHammerJ.
A simple modpack banning tool.
Just place the UUID file of banned people in your config/Bans folder or recompile this mod with hardcoded UUIDs in the BanLoader.java
Usage cases: Serveral Servers running your modpack and you want to ban people over these servers, just add the UUID files or the new compiled mod in the next version.
WARNING: DO NOT SHIP THIS MOD CLIENTSIDE. IT WILL CORRUPT SSP WORLDS ON BANNED PLAYERS.
