When you subscribe to the 'firehose feed' (
https://hnrss.org/newest?link=comments) you get to see a fair amount of those; most are outright spam. There's even a degree harsher than what you see at the linked article here, namely a page that's blank except for the orange bar at the top. I get to see those every day; just a few minutes ago I got this:
https://news.ycombinator.com/item?id=42607034 which was advertised in the RSS feed as "When Did Trolling Become Inextricably Linked with Pedophilia?"; from a quick scroll down the linked site (yes, you get to see all the original URLs as posted in the RSS, flagged or not) I'd say it's an unappetizing piece of writing that regurgitates recent right-wing talking points, a lot of made-up stuff, so Good Riddance in this case.
