Hello! This is a very simple plugin I made. Some features aren't implemented yet but I expect to add them in the next update. Overall, this plugin doesn't require any permissions/commands, you just have to set a maximum number of lives for your players and you HAVE to enable the whitelist so that players won't be able to join back in the server (I'm planning to automatically ban them for a custom period of time, probably it will be added in the next update) and that's it!
Thank you so much!
