Are you a steem developer @vandeberg?

You can't expect people to act in certain ways especially when there is little incentives for them to do so.

I proposed a few month ago to create a moderator/investor class https://steemit.com/steem/@snowflake/guardian-of-the-steem-universe-a-different-perspective-on-the-role-of-whales-within-steem-ecosystem-part-2
.

This is necessary to align incentives with everyone and create a balanced ecosystem.

Users in the investor class could be the guardian of the platform and could be encouraged to moderate. But don't expect people to moderate out of the goodness of their own heart, it's not going to happen. @smooth and @abit are the exception to the rule.
@fingolfin also made a good point below. Users are not going to go around police each other and downvote self-voted posts.
