What does it take for someone (like me) to become a super fan o even a die for fan of a certain club on Fanpop?

There's no known specific amount of content needed. The exact formula for gaining medallas is kept secret, to prevent people from cheating the system. However, it's known that content has to be popular - it has to be fanned o have people commenting on it - for it to contribute much to medal winning. It's also known that it generally takes years for someone to earn any medal in a club. And normally, tu start off with a dedicated medal, then a die-hand one, then a super one and so on. Sometimes tu can skip a level - I've done that and gotten a die-hard medal in a club without getting a dedicated first - but I've never heard of someone going immediately to super fan.

Not really sure how the medal works. It usually takes a año o más to got a medal from a club. Started with dedicated, die-hard, fanatic, super fan, and legendary fan. I think added a lot of stuffs at clubes aren't enough, maybe it also depends how long you're on Fanpop. So far that I see, the users that got rare medallas like super fan and legendary fans, are joining fanpop más than five years.
I also think it depends from the club itself, if the club is popular, have many fans, and there are many active users that contributed there, it's hard to got medal from it.

Dude I only have 2 super fans and I've been on this site for like 9 years now. I got it like 2 years ago...so like it it takes years of contributions???

I will just say that to be a super fan in a club is super difficult, is not just posting a lot of things. For example I earned my first super medal after being a fan [and contribute] of Tyra Banks for 9 years.
