IME, a certain amount of self-promotion is totally accepted (even expected) at HN. But dude... you have had an account for 3 months and in that entire time ALL you've posted is self-promotional content. To the tune of about 15 submissions to your own site, in 3 months. That's 100% going to get you the wrong kind of attention.
From the HN guidelines[1]:
Please don't use HN primarily for promotion. It's ok to post your own stuff part of the time, but the primary use of the site should be for curiosity.
