These are lists of known abusive accounts.

Now, perhaps another account that puts out a daily report of posts by authors not on these lists, that emphasizes not getting any, and/or up to the median, in rewards.
It could be the anti-trending.

If there are too many, I would focus on hive focused content.

We had a daily 'newspaper', but it proved less rewarding than the guy was willing to work for.

So, posts at or below 15 hours of age, listed daily, from the bottom of rewards up.
