This is one of the very few sites I've flagged in my 3+ year HN history. Here's why: HN seems to work because we focus our attention on high-quality posts and "content-filled" comments. Low-quality (and sometimes unpopular, unfortunately) comments are penalized.
This project -- if it does what it claims -- seems to focus on people that create low-quality comments (i.e., "trolls"). In a way, it's rewarding them for their behavior. (and yes, I realize the irony in my comment).
Also, it blanket labels anyone meeting its algorithmic threshold as a "hater", when in fact they may just have written something unpopular.
So I'd prefer for people to create value using HN's API in more positive, constructive ways.
Just my opinion, obviously.
