I know. I disagree with the practice, especially when I look through the history of the account and see no flagrantly offensive remarks. HN mods might think this site is a temple, but it's disrespectful to waste someone's time and mislead their expectations of feedback for months at a time.
My assumption is that because they have the username 'unethical_ban' they probably understand that they broke the spirit of the Hellban, but did so intentionally.
This account is not intended to be a novelty account; you can see I post relevant discussion most of the time. I am, however, someone who was hellbanned for quite some time for an admittedly less-than-stellar post. One facetious remark got a 900+ karma, 3-year old account banned.
I'm sure anyone using the term hellbanned knows what it means. Sometimes automatic hell banning makes mistakes or is heavy handed (not sure what the algorithms are); some selective civil disobedience corrects the issue and lets the user at least ask admins to find out why.
