Prevent players from hiding their names
I had this issue on my server on the weekend. A player was joining and was being quite annoying, however whenever he spoke, the voice chat name always came up as ‘unknown’.
In order to kick/ban him from my server, I had to alt+tab out of the game and go to my servers control panel to get the player list.
I noticed that in the player list on my server there was someone with a tag on his name, that i wouldn’t see in the game. So I assumed it was him, kicked/banned him, and the annoyance stopped.
I’m not sure if this was just a glitch, or if it will be a way for players to troll/grief in games, but hopefully you can do something about it.
