Just a simple blacklist with some added features to customise it, like working mode, kick message or priority of listener.
A pretty good feature is the listener priority of blacklist: if set to 'first', it's working before all verifications of client, so it can avoid creating empty accounts or interfere with other listeners
Also this can allow a blacklist of regex. If a nickname matches with one regex of list, it's also kicked.
This is very useful for servers that suffer raids with different nicknames each time.
To control the blacklist, is very simple. Just use the command 'blacklist'.
And to see usage of command, use 'blacklist help'.
Open an issue if you have a suggestion.
Prebuild relases can be found here
You have just run command ./gradlew :build or execute script build.bat (for Windows) or build.sh (for Linux) and the plugin will compile automatically.
Simply place the output jar from the step above in your server's config/mods directory and restart the server.
