There's nothing to disagree on regarding downvotes as I never said downvotes were the solution.
One account should not be able to vote on more than a certain amount of proposals and there could be a predetermined floor instead of relying on the return proposal to fulfil two functions. The return proposal was necessary to ensure the pool didn't get robbed by selfish proposals, however, allowing whales to actively control its level is neither fair nor ideal.
A fork could say proposals will not pass if they don't get at least x votes from at least y people, considering active hive. Everything below the floor will be returned to the DAO. The return proposal was a stop-gap measure to cover an oversight in the SPS/DAO and should be made permanent and fixed, or floating on some level based on some pre-determined function of active hive.
