Every account can choose to pay out in 50/50, 100%SP or decline payout. They don't want their info posts to be paid from the blockchain, which would shrink everyone elses payout value a little, so they use "decline payout" option. This is not due to downvoting this post (maybe that's what you were thinking?).

I am a little startled that you managed to get rep59, and did not know this.
