I like the rewards. I would not opt out. I feel you are over complicating it. Perhaps the best solution is too boring Is there not a more equitable system that discourages the behaviour i wrote about above and encourages people to zap content that actually resonates with them, rather than what they think 'might" be top? We don't actually know what would really be "top" because the zapping behaviour of users trying to get the best result for themselves from the system skews the results.
