All Minecraft servers are public by default. But there is this feature on Minehut where users can press a random server button in the Minehut lobby to join random servers. And someone probably joined yours from that. You can whitelist your server so only people you allow can join.

First run the command /whitelist on to enable the whitelist. Then do /whitelist add <player> and only those players can then join the server. You should also disable the visibility of the server in the settings tab on the panel so it also won't show up in the in game server list in the Minehut lobby. 

Also you can't delete Minehut servers so I'm not sure what you mean by that. And if you have proof of this person griefing, you can report them here to get them banned - https://minehut.com/support
