Ask HN: Am I using this site correctly?

I mainly just post things that I create a-la github under the text "Show HN:"

I'm wondering if this is a misuse of the site as some I don't really see other people doing the same. Is what I'm doing incorrect?

Also, recently there have been stars next to my three most recent submission, which, combined with the fact that no one seems to click on the links or give it any votes, makes me suspect that I may be banned/under probation. Would something like that happen in my situation?
