Yes, a bunch of positive comments from accounts without much posting history appeared in this thread. I assume that the OP's friends got wind of their launch.

We tell founders to avoid that (scroll down to the bold part of https://news.ycombinator.com/yli.html for how we try to scare YC founders into not doing it!) - but to be fair, (1) this is not always easy to control, and (2) people posting such comments think they're helping and don't have enough experience of HN to realize that it has a counter-effect.

I'm going to move the overly sus ones to a collapsed stub now. (https://news.ycombinator.com/item?id=45988584)

i agree, things are a bit too kind. give me some more feedback.
