There is a problem with having groups here that are completely abandoned and are just taking up space. This is mostly due to the creator of the group, the administrator, account being terminated by being perm banned or deleted. There are groups that are active but have lost their administrator and have no one to administrate or are left to the ops who remain in charge.

I propose a solution. The groups should be tied to the original creator's account. That way if the creator's account becomes terminated, then the group becomes terminated as well. However, in order to safe guard a group's continuation and an administrator succession, there should be an option where the creator of the group can list perhaps three to five successors, in order of preference, that will have full administrator abilities should the original administrator's account becomes terminated. E.g., if the administrator picks A, B, and C as successors, then A would get it provided that A's account is not terminated as well. If A's account is terminated, and the administrator did not replace A before his account was terminated, then B would get it, etc. The new administrator could then, of course, pick new successors or leave the original ones picked should something happen to his account.

This solution could be applied retroactively in order to get rid of abandoned or stagnated groups who have no administrator due to him being terminated.

In reality I feel that the type of people who become perm banned or delete their accounts won't have the foresight to use such a feature.

Then their groups get deleted as stated instead of lingering. That is the point.

The moderators can get the option of taking over the group once the admin of a group gets banned or deleted.

If they have no moderators for their group then have the members have the option of taking over...

Maybe deletion if they have no mods is a good way to go... although those who delete should have deleted their group first ...
