I didn't get this - you mean to say if the paid content in the promoted or other feeds if gets voted their resulting rewards can be burned ?

Not the rewards, just the money paid to be promoted. The promoted posts (fine fine fine native ads) then "compete" for views in the relevant tag feed or general trending feed. I've offered this before many times: simply take the existing "Promoted" mechanics and page, and spread it throughout the feed like Reddit does. I want to see SBDs burning here!!!
