When you ban a player in the lobby , they still remain on the server until they switch realms. So banning a bot spammer can only be fixed in that server / realm . Just a note to help avanilith
I had that exact issue today. Player was advertising another server on OpPvP. Told him how I ''hate'' the server and advised him to advertise in the lobby. The ban hammer spoke. :lol:
We're aware of this, simply kicking them will not allow them to reconnect once they're banned in the lobby. If wish to suggest something regarding this then you may in the suggestion section located here: http://www.mineverse.com/forums/suggestions.11/ Archiving.
