For sure, I just don't think there should be a "threat" over them that if they self-vote they will eventually get downvoted as that sentence made it out to sound. It's in everyone's best interest to use their upvote mana to grow their influence here and curators should look at different activities of authors before curating since most of us here aren't that "valuable" in content in and of itself. (I.e. anyone can write what you and I write, we're replaceable), but what stands out is the social aspect, where genuine attention is being driven, history of the account, etc. If someone spends most of his mana on himself then it'll be their loss eventually and they should see their earnings weaken compared to those using their mana better. If they spend it on themselves constantly, such as comments, low effort posts, etc, then yeah expect some downvotes.
