People are welcome to post their own stuff as long as it's part of a mix of unrelated/interesting submissions. What gets accounts "super deranked" is when they only post their own stuff or use HN primarily for promotion (this is in the site guidelines: https://news.ycombinator.com/newsguidelines.html). Your account hasn't been doing that at all, so you're fine, and certainly welcome to post your articles if you want to.
Edit: I sent you repost invites for https://news.ycombinator.com/item?id=36211059 and https://news.ycombinator.com/item?id=35881175, both of which are great HN submissions. If you use them, the reposts will go in HN's second-chance pool, so they'll get a random placement on the front page. If you don't want to be bothered in this way, please say so and we won't do it again!
