It's hard to tell who's manually curating or not, it'd have to be decided on in some different ways if you mean the DHF would reward them additionally compared to autovoters, votetraders/selfvoters through delegations, etc, which this place is swarming off.

I haven't been a big fan of the DHF, there are a few things I could imagine asking for help for there to help hive out but have attempted to scrape some rewards off of the posting reward pool for now in a smaller scale to see how things develop - for instance POSH, onboarding and curation&moderation.
