Apparently, this is the comment that got my old account banned: https://news.ycombinator.com/item?id=4342935. I'm not sure though, it's just the last one on the profile before they go dead.
I'm guessing that got caught in the spam filter for use of the words "jewelry" and some of the other keywords in the Amazon link. This is one of the unfortunate side effects of running a startup that happens to be in a field that generates a lot of (affiliate) spam.
I did like my old account.
