Trying to avoid war-time spies
Just an idea that I haven't seen addressed in the forums. If you're at war, a member from the opposing clan can join your clan and spy on your cc troops, trap placement, etc. We've stopped it a few times, but a few other times they managed to sneak in.
Would there be a way to prevent folks from joining a clan they are warring against?
Sidenote: What a pathetic way to conduct business. If you have to spy to win, then you are just sad.
Spying is a part of the game
As a U.S. Army Vet and a player of this game, spying is and should be a part of the game. I don't do it myself and my clan never accepts anyone during war. Your idea won't stop it anyways because many guys have second accounts and keep them in other clans.
