KICKING OUT CLOSED ACCOUNTS

Plain Admins have to do it one-by-one (which allows you to keep the self-closed accounts and remove those closed for cheating or abuse).

If the account is closed for it is gone there is no account left.If he/she made comments they are still there
The account is still there but he/she cant use it..

No, they (chess.com) only adjust the membership counters and they do not remove closed accounts from the group.-LPS

Closed accounts are still in the database and depending on the closure reason, their content and group memberships stay. For self-closed accounts, the player can open a ticket to get the account enabled again.
Is there any way for admins to kick out ALL the closed accounts from their group?
I know that chess.com periodically removes the closed accounts but they dont remove all of the closed accounts..
So, do they remove closed accounts from the group once in a month?
I think chess.com should make an option for admins to kick out multiple members at a time because there are many closed and inactive accounts that takes forever to remove one by one.
