Why am i not anymore one of the best contributor on The legend of Zelda club?

I dont understand, before i was onfe of the best contributor, but now not anymore even if i posted more stuff than the other "best contributors". I check how much stuff they posted in that club and they all posted less than me. And one of them doesnt have even a medal and one a green one, and i have a yellow, so why am i not anymore there?!?!?
