Your comment inspired me to look up more information on HF20. The last thing I read on it was many months ago.

If I am reading this correctly, HF20 eliminates the advantage to the author who upvotes himself right at the time of posting (the auto-upvote).
I did not find anything that would eliminate self-upvoting entirely.
The method I use attempts to reward curators who vote on my posts within three days a greater curation reward by enlarging the total curation pie. And that curation pie is distributed more towards the early voters.
Did I miss something in HF20?
Thanks! Have a great weekend!
Steem on,
Mike
