I kind of mixed up the message of your post with my own thoughts about empty comments across the whole platform. I understand where @yintercept is coming from in his comment, there is an art to some of the more plausible looking empty comments, but when you get down to it they're meaningless.

My concern is with @amr008's engagement project within the POB community. I've noticed some accounts which rank well within his script and receive heavy upvotes when the majority of the comments are quite frankly garbage. I don't see this as proof of brain and I feel like it's a fair use of downvote for disagreement of rewards (I'm not sure how this would affect @amr008.pob's curation rewards, plus I wouldn't want to hinder dividends ((will probably get strangled in my sleep)) and the accounts growth).
