While some players stick to the rules and resist endless assaults ....
Some others cheat the system
There is no way in the game to LEAVE a clan while you're boss, to make attackers think you give up and by miracle a day or two later you're again the boss
If you leave the boss role of a clan, the clan cannot have a boss anymore, no matter how you try, unless by cheating the game.
Especially when the guy who cheats is a known lesson giver...
