Like the person above me said, they onyesha how dedicated wewe are to a certain spot.
To get them wewe have to be a Jack of all trades. That means, creating pop chemsha bongo questions, commenting on polls, adding pictures, uploading vids, all that good stuff. (JUST MAKE SURE that the stuff wewe add, especially pictures, havn't already been uploaded kwa someone else, au the pop chemsha bongo maswali wewe add havn't already been asked. It's not only inconsiderate, but super annoying). Anyways, the stuff wewe add needs to get good ratings, au a lot of people participating. If wewe add enough stuff, you'll get medals. Like I alisema though, it's all about the ratings, so be a nice fanpoper and rate other people's stuff. They'll return the favors ;]
