Well only one at a time. Then as each gets banned I make another one. Note that they get banned if I just visit HN from the IP in question no posting required.
You’re not really comprehending what I am saying. If I create an account, never post or comment, and just browse HN from the IP in question, that account will be banned. It has nothing to do with behavior.
If you're concerned about a specific IP, and haven't been abusing HN, it should be easy to clear up by emailing hn@ycombinator.com. And even if you have been abusing HN, we're always happy to unban people (and/or their IPs) if they give us reason to believe that they've taken https://news.ycombinator.com/newsguidelines.html to heart and will follow the rules in the future.
This is not accurate based on my testing. If I browse to HN while logged in to my account from the affected network, that account can never post properly again.
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.
The article is about bringing transparency to HN operations. To allow what I believe to be a factually inaccurate statement by one of the operators just stand as the last word is against the spirit of the discussion.
Have you considered, perhaps, changing your behavior?
