pretty much what hashirama said and what you call cheating is in fact a valid strat for wars and when your complaining about is gnw (great ninja WAR) as-well as it was common for all to have spys in your opponents base and it is part of the game but most severs from what i seen don't need to worry about it

well besides kill the game as they can not add in anything that the cn does not have/do its just you guys forget its a game for fun people spy thats life kick them from your group problem solved or have your boss and seniors move poeple at the last 10 seconds
