"Input and output" players in clans

today is very complicated, if not impossible to recruit members for the clan. one of the factors is that there is no punishment for players who enter and leave the clans no reason, for example: a player enters the clan and for a few minutes and ask troop shortly after receiving leave without any shame. in my opinion if there was any punishment for such clan output: out of a clan, you can only enter another 48h later ... it would be fair and evil player in general learn, do not say all, but many would stop this comes and leave.

obs: sorry for my bad English:(

What about players who have alliance clans they move in between, or request and leave clans? What if I join a clan and decide it isn't the right fit for me and leave, I should be penalized for that?

If if your clan has an problem with people joining to just to get troops, then make some rules....example: must donate 20 before requesting, if they request straight away then kick them.
