You can't attack another user like this on HN, regardless of how wrong they are or you feel they are. You may not feel you owe them better, but you owe this community much better if you're posting to it.

Since you've unfortunately been breaking the site guidelines repeatedly (and egregiously, e.g. https://news.ycombinator.com/item?id=29237513), I've banned this account.

If you don't want to be banned, you're welcome to email [email protected] and give us reason to believe that you'll follow the rules in the future. They're here: https://news.ycombinator.com/newsguidelines.html.
