As stated in the OP, clans are not getting deleted. They are getting their official status taken away. Therefore, if you just want your clan for the memberlist of dead people, you get to keep that.

And we want to avoid adding an inactive rank because clans could just shove people there who might not exactly be inactive but rather haven't contributed to in-game activity, thus enabling a loophole to pass the check nonetheless.


EDIT: Oh yeah SP clans. We can make an exception for them if enough of their members actually post/make replays. If none are posted then we can't exactly gauge if they actually even make the replays, y'know.
