Honestly I have no clue how it works; I've been under the impression that it's random. I have 記事 with like 7 ファン that aren't on the 一覧 but ones with none are?
ゴールド must also be earned によって people commenting on and reacting to content, または even just によって viewing it. I would expect content which'd been fanned to be in the highest ゴールド earners though - I agree with あなた there.
I have no clue, but I think that's possibly happen if it made the front page (if anything that we add doesn't have any ファン または faves) It happens to me when I add a video of Pitch Perfect trailer and that video made the front page and suddenly it appear as all time ゴールド produce.
