That's probably why you're not getting what's wrong with your scheme. People are supposed to be curated for the content, effort and/or other contributions to the ecosystem. Not just because they give you delegations you can upvote them so they can circumvent having to post 10x per day to self-vote all those posts and not share their upvote mana with other unique users on the platform.
What you and your delegators are doing are not fair to the rest of stakeholders and regular users on the chain according to the blockchain rules and consensus of how curation should work.
