The blogger that bought 1 M usernames for 5$? FB called him and said: shhh

Responding here as your latest post is indeed dead: http://news.ycombinator.com/item?id=4737582 I'm not an editor, but might be able to offer some insight.

Most likely, it's not your site that is banned, but your account: you've probably been "hell banned". This is probably statistical rather than personal. 20 posts, all to the same site, with few upvotes definitely fits the pattern of a spammer. It's also possible that the post I'm responding was flagged by users: unlike the interviews (which are great), this one is weak and could legitimately be considered "blog spam".

Your recourse is to contact pg or someone else prominent in HN by another channel (email, most likely) and ask them to consider your case. Alternatively, unless your site has also been banned, it may be easiest to start again with a new account.

Personally, I think you're skirting at the edge of the rules. While much of the content you are posting is high quality, it's not clear that you are posting it because of that. As it's your own site, you certainly have a self-interest in promoting it. While not explicitly forbidden, it's definitely frowned upon to use HN for PR.

But I really do appreciate that you are not using puppet accounts to do so, and presume your intent is true. I've just reposted your Wing Sail article so you can check if the problem is with your domain, or with your account. Also because it's a good article, and deserves some attention: http://news.ycombinator.com/item?id=4737760

Good luck!
