Are you inviting people to clubs based on clubs they're already members of, or just inviting randomly? If it's random I can see how people could view it as spam, but if you've seen that they're already a fan of similar things then it's relevant.over a year ago
The best way to let like-minded fans know about new clubs is to post a link in a similar club. (For example, if you create a club for a character, post a link to it in the club for the show/movie the character is from.)over a year ago
