This is exactly what I argued about with some dude here in my own Steemhunt. I thought I'd made a genuine and worthwhile contribution whereas he just put up a few pictures of Star Wars.
Moreover, he got an upvote from Haejin, which would have been fine on any other post, but with Steemhunt it has obvious implications. Haejin knew Steemhunt would upvote 100% as the post would rank #1 which would make him earn high curation reward. Somehow, it didn't however. Bad timing I guess.
According to curation estimator on steembottracker.com Haejin did not earn any curation reward whatsoever. On the other hand, Steemhunt earned about $14 USD, so at least there's that.
I'm not accusing anybody here. Yes, I agree there's the argument that the post is about the sale. I just think that there are places where manual moderation of content should be applied. This is one of them.
