I don't see any evidence that r0fl's comments are astroturfing. Sometimes people are just enthusiastic.

I appreciate your concern for the quality of the site - that fact that the community here cares so much about protecting it is the main reason why it continues to survive. Still, it's against HN's rules to post like you did here. Could you please review https://news.ycombinator.com/newsguidelines.html? Note this part:

"Please don't post insinuations about astroturfing, shilling, bots, brigading, foreign agents and the like. It degrades discussion and is usually mistaken. If you're worried about abuse, email [email protected] and we'll look at the data."

it's a fair concern. but, we don't know r0fl. and we are not astroturfing.

even I am surprised with how many opnely positive comments we are getting. it's not been our experience in the past.
