Removing downvotes on a Proof-of-Brain platform like Steemit would likely accelerate low-effort and AI-generated spam rather than stop it. Without a penalty mechanism, creators could flood posts and comments with minimal risk—only upvotes matter for rewards, so anything that slips through curation gets paid. Human curators already struggle to keep up; AI content scales instantly, and the reward pool would get diluted faster as volume explodes. Some communities might self-moderate via ignoring or blacklisting, but overall quality and trust would probably drop.
