It was funny to see to be instantly judged for that behavior on a person's post.
It's your SP, your portion of the inflation, you are the one that should choose how it's spent, not someone else... I do something very similar myself, I autoupvote a lot of Steemians and try to shuffle around my votes to change or even to decrease % to allow more people inside the list as I power up more SP, ofc, always trying to keep the quality of the content that I reward to the best possible. I also leave some votes for manual curation for stuff that I see that I want to reward.
