Why I ban members, but they can still join my club?

I banned them 10 times!
It is not always I misclicked it
For example: I banned @satammu2003 more than 10 times in "Chess.com's Learning Club." and my club "WorldWide Chess.com's Club", still he finds a way to jump in our clubs! How so!?
And @ArizHusain banned me from his club "Chess.com Friend's club", but I can never join his club!
You can't join his club because he banned you from it
