this change will work only if:
A. big accounts that are selfvoting, bitboting spam or whatever you do (not you as you) to get most of the steem, now start to spend hours on steem looking and reading/watching content to upvote. but that would be hard because on steem you have a lot of #belowaveragecreator s (that are on steem just because they suck and would be somewhere else making a lot more money) that are here just to take money from people that invested and are doing everything to make steem great. not really seeing that happening.
B. enough big accounts start downvoting selfoting, bitboting whatever you do to the point that the other side stops doing that. small acc will have no influence on it and will only be bystanders in everything, as they always were and as the system is made.
