I think it would be convenient to have a block list for clubs basically where certain people cannot join if they are blocked from the club. Since almost every club wall you see a banned list of players instead of taking up wall space just add another tab for blocked list.
Or just block them and if they request to join check if you have them blocked. there I solved your problem /lock
I like to reject em but I agree w the ban list simply bcuz not all my admin would know they're banned and it's too much to message an such then if they get a name change and they join cuz you dunno it's them?♀️?♀️
Make it work so the banned person can no longer apply, just like a person can block someone. Then it works.
