At this point, three people, including a mod, have suggested you contact the mods via email to investigate further and get to the bottom of your particular situation. Have you done so? If not, that does seem to be the most constructive way forward.
Edit to add: Without more details from you, I can imagine the mods being hamstrung with respect to figuring out or explaining what's going with what you're observing. Likewise, there's nothing preventing you from continuing your comments here while also emailing them. Particularly as it seems you'd like to continue to participate on HN. I can imagine you'd prefer to do so without the hassle you're currently experiencing.
