It's already been said in the thread op. Honestly, it feeds the whole board. Look at /vp/ when we are off hype season, it's dead, there is nothing substantial here. The board needs leaks/ hype season to bring in posters, but it's gotten out of hand. There's about 2 new "leaks" posted every hour. Then there is the whole attitude of the board when you don't believe something that gets proven later on. Like the gen 5 starters situation. I didn't care either way, but you would see thread after thread of the winning side shit talk the people who didn't want to assume that every leak that gets posted here is legit. It makes no sense.
This whole situation may be cause this board is only about one topic, pokemon. I wonder if the mlp board functions the same way. I wonder if this board is just containment. It's very telling though that the only legitimate leak this hype season has been posted on a different board.
