Deny New Usernames | UniqueAgain

UniqueAgain - Keep your server safe until you're ready to update!

UniqueAgain is a type of whitelisting plugin that allows anyone to join your server for the first time, and any time after. Unless... They've changed their username. That's right! UniqueAgain will kick anyone from your server who changes their name.

This is done simply by writing the UUIDs and usernames of any player when they first join your server (with this plugin enabled), and kicking them if the username doesn't match the UUID! This is EXTREMELY useful to those server owners who aren't quite ready for the update, and want to ensure that players aren't taking advantage of the recent name-change implemented by Mojang.
