Scrap that - here's my final thought...

@steemcurator01 doesn't blindly vote on the posts that are selected as you'll see from their historical comments. They read the posts and if a selection is made that they feel is underserving, you'll see a polite comment along the lines of "was there a shortage of quality content this week?"

And then by no coincidence, you'll notice that these people aren't selected as curators again.
