Yes a separate pool for downvoting would be ideal because we would each benefit from having the choice to use our stake both to upvote and downvote. If I did not have to choose between an upvote and downvote I would use my downvoting share to counter abuse. When it is a choice between an upvote and a downvote, why bother fighting abuse when the vote can instead be used to reward others doing good work, run a voting bot, and/or self upvote?

A separate voting power for downvotes would also remove the sigma of doing something wrong and eliminate the huge power available to those willing to use the downvoting power.

Thank you for this discussion Tim!
