Stop changing of sides in Warfare

[Sparticus76]

I did a search on this and couldnt find anything on it to my surprise. Warefare is fairly popular and you get people finding out the where abouts of the HQ, changing sides and then going to the location to reak havok. Is there a way to stop this?
Can you list who has joined on a particular side and then kick them if they try to join the other?
