I think the problem is there is too much reward to self vote if the price increases. It becomes a reality to invest, self vote, dilute the reward pool while delivering no value to the community.

If you invest enough and self vote all your own posts, others to vote your posts as well purely from a curation angle. They will flock with auto votes trying to ensure they are 1 min before your vote, knowing they can can get 5-10x their vote value every time. This is one area that I struggle to see how we evolve past.
