16yo looking for friends to play the forest, my world (i speak italian and english very well)

Am getting griefers on the server. It is a dedicated server. They come in invisible and delete blueprints and cover players with bombs.

I have it set to no cheats. Will enabling VAC help?

Is there anything I can do to stop them?

I accidentally banned myself today. Lucky I had a copy of the banlist file to restore.
