I think @contentking has a valid point. Of course to a certain degree it is normal and OK that popularity plays an important role in a social media platform, but in my opinion since HF 19 self-voting (or using multiply accounts which upvote each other) or kind of 'circle-voting' (A upvotes B and C, B upvotes A and C, C upvotes A and B) between big account holders has become much more beneficial. The reasons for that I described here (your opinion would be very appreciated).

In the same article made a plea for implementing 'diminishing returns' which I described like this:
"How about if after each vote on a specific account (including ones own account) each further vote on the same account would lead to significantly less curation reward for the voter and less profit for the upvoted account? Thus, when upvoting an account which I had already upvoted before, my voting power would be smaller than in case I upvote an account which I didn't upvote before."

it is completely normal that a system will be exploited if possible, so I don't mean to blame anybody for doing anything. However, I think a system which makes self-voting less attractive would be better than the current one because it animates every user to upvote many other users and not always the the same ones (respectively oneself) again and again.
