Ask HN: Please raise the ban on my URL?

Hi HN team, This is the 3rd time this has happened when I try to paste a link of my blog. It appears on my page (maybe because of a cookie?), but doesn't for the rest of them. Here are 2 screenshots one with the post for Interviewstreet (http://awesomescreenshot.com/02f96cy3d) and the one without it (http://awesomescreenshot.com/0b996cqf4) at the same time. I am not sure what we did wrong, but could you please look into it and let me know. Thank you.
