The idea about the clans and players

Hello!
Sorry for my English. I use a translator.
I would like to propose the idea to increase the responsibility of players to the clans that they choose.
I'm tired of players who run from one clan to another, or leave during a clan war.
Propose to introduce bans for these players. For example:
If a player has been in the clan for at least 3 days or left of the clan during clan wars, that player will not be able to join other clans for weeks.
As well as the profile of each player to appear surprising number of abandoned or derelict clan clans during a clan war.
This innovation will help players responsible approach to the choice of the clan and create a more friendly and decent situation

Or at least make that head of the clan could ban players at will. That is, that banned the player could no longer join his clan.

Well, support the idea! How many players can run around the clans
