Thanks a lot for the explanation,

This can push profiteers to spread their votes but doesn't guarantee that they will vote for genuine users, the rewards mechanism could still be manipulated by the creation and use of several accounts to extract value and affect the median to facilitate the process of extraction. As long as there is a human factor in the equation, things won't work perfectly, we could think of something to mitigate the problem by making it harder and harder to manipulate the rewards mechanism, but we'll never solve it completely. Hence why investors may find that investing in STEEM is a foolish thing because they don't have the complete guarantee the value is being created and not extracted through manipulation.

Greed will consume this blockchain,
