Let's try a different way. I've marked your current account legit so as to exempt it from HN's anti-abuse software. As long as you keep following the site guidelines, it should be fine to stick with this one from now on. If you'd rather use a different account, let us know at hn@ycombinator.com.
I'm not sure what past statement you're referring to, but HN's software doesn't shadowban anybody just for accessing the site from a specific IP, so whatever you're experiencing, that can't be it. Unless it's a bug we haven't seen.
