How do bạn xóa các câu lạc bộ bạn have made?

I'm not sure if bạn can, hoặc how to, but if bạn no longer want to be associated with it bạn can still unsubscribe to it. Just go to the các câu lạc bộ section on your profile, find the club and hit unsubscribe. The club will still be there but you'll won't be a part of it anymore.

báo cáo it.

I think there's no such a thing as a "Delete club" button.
But, bạn can báo cáo it hoặc ask people to báo cáo that club.
Then it will be surely gone.
