You have a cool site! You should know that the last four links you submitted to HN went [dead]. Open your submissions in a private window (
https://news.ycombinator.com/submitted?id=icely), and you won't see three of the four. This one is only visible because I vouched for it (
https://news.ycombinator.com/newsfaq.html#dead). I think the spam detector caught you because you've been submitting links from the same site from a new account. I'd email hn@ycombinator.com and tell them you're not a spammer.
