Although I am on the side that thinks this is not a big issue requiring emergency attention I will suggest (repost from what I said earlier in the thread) a way they could approach this that does get rid of the dead one person clans without disrupting the ones that are merely dormant.
- Have a waiting period were no members are active (Do not log in) at all. Since this idea prevents the one the clan belongs to (the leader) from losing anything the waiting period does not have to be months. One season is sufficient.
- After the waiting period is over the clan is tied to the leaders acct. If he ever comes active again he is asked if he wants to revive his clan. if he says yes the clan is reinstated with all xp points. war wins, etc.. and the leader is its sole member. From there he is free to restock it and move forward. He has not lost anything nor had anything taken away.
- With the clan tagged to the leaders acct it can then be removed from the game. Unless the leader ever becomes active again and asks for it this clan will never be seen in COC again.
The inactive acct (the leaders acct) would still get handled the same way the game does already. It is largely hidden from view so that it with its full collectors that would give loot, does not come up in searches. (So that us players don't get that loot)
