    Hi there,
    Looking at the documentation it is possible for the host to kick a Player with RemovePlayerAsync(); however the kicked player can just join the Lobby again and again.

    Doesn't seem like there's a way to ban a Player so they cannot join the Lobby again, I think that should be added.

    I don't know about Lobby, just NGO barebones. If I wanted to uniquely identify a client, I would have it generate and persist or load the existing GUID and send that to the server with the connection approval payload upon connecting.

    The server only needs to maintain a HashSet<GUID> _bannedPlayers and check if the connection payload's GUID is in the ban list. If it is: connection denied.

    Of course malicious players could find a way to modify the GUID, either by modifying it in memory or by modifying the payload packet(s).
