Authors cannot control what curators earn. There is a little known feature to turn off curation completely but no one uses it and it doesn’t tell the voter this is the case.
I earn the exact same curation rewards as everyone on Hive. I make nothing off these burn posts and in fact it prevents upwards of $330,000 sell pressure a year.
I can vote this dudes shit posts or the burn posts and I get the exact same curation rewards. There is no special incentive to vote them outside of the reduced sell pressure and reduced inflation.
