Yes, anyone could शामिल होइए your club, if द्वारा that आप mean becoming a प्रशंसक of it. It's not possible to restrict any फैन्पॉप user from becoming a प्रशंसक of any club on Fanpop. Of course, क्लब्स aren't owned द्वारा any particular user, even if that user created the club, so it's not really "your" club any और than the फैन्पॉप Users club is "my" club.
