How are people changing the game mode to a server with a campaign that does NOT support that game mode? They keep doing this to my server. How can I stop this?

Some Servers are modded ones, and some of 'em have a bug for an example: You join to a Campaign Game, then you see that it's Versus not Campaign, in this case get out and join to another one if you want, or make a lobby with the Best Available Dedicated and it will choose a Server randomly.

The thing is that it's for my server. It happens every now and then. Somehow they change the game mode with a campaign that is not supported by that game mode. For example, they'll change to survival mode on a map that doesn't support Survival mode at all.
