哈哈 yeah I asked this 问题 to someone else as well when I first joined Fanpop.
the only secret to it is to post a BUNCH of links, photos, videos, picks...etc onto a particular spot. Make sure the stuff 你 post is good because to get a medal ASAP, it all depends on the ratings 你 get for each item. So if most of your stuff is rated 4 或者 5 stars, then you'd be getting a medal (or upgrading) pretty quickly, but if there's no 或者 low rating, then it's gonna take longer.
so basically, 你 need to spend a lot of time on one spot if 你 wanna get a medal, otherwise if you're like me who just likes to chill and hang around on Fanpop, then it can take a while~ :D
There isn't an actual answer to that, the f4 keeps it secret of how many contributions u have to make to a spot to get a badge. It does take a while though! It took me 5 months to become a dedicated 粉丝 of a spot!
