"Screw You!" is a very simple plugin that when used, shows the Minecraft demo screen to a player. It's not dependent on ProtocolLib, just you need to have 1.20+.
Installation Instructions:
1. Make sure you are running a 1.20+ server.
2. Place the plugin in the plugins folder.
3. Restart the server. Do not reload or the plugin may cease to work.
4. Enjoy trolling!
