As you know, you can't attack other users like this on HN, regardless of how knowledgeable you are or feel you are. Therefore I've banned this account. If you don't want to keep getting banned on HN, please follow the site guidelines.

Your shop, your rules, obviously. I think that's a shame fwiw and write now against any bans based on a cursory read of their last 3 months of comments or so. As I also did against the disappearing of the comment itself.

You may know better for many reasons. I note our concerns and goals are not necessarily aligned. YMMV.

When someone has a long history of abusing HN, the standards are different. Normally I'd just post a warning in cases like this. Actually, even if this were the first time this particular account had posted abusively, I'd have used a warning rather than a ban. But there are enough abusive comments in this account's history also, and this comment was a particularly clear case of reverting to a long-established pattern.
