Why is this flagged?
Given the content, I find this suspicious.
I looked at the flags and they seem to be legit flags from legit users. My guess is that they thought this was below-the-radar drama that wasn't on topic for HN. (I could make a "people who flagged X also flagged" list a la https://news.ycombinator.com/item?id=46771900 to support the point, but it's a time-consuming pain so I'd rather not!)
Edit: after looking at this more closely, I have a counterintuitive (to me at least) take: I think this is interesting enough to transcend the usual categories. That is, we'd normally downweight this kind of post off the frontpage - but in this case there are so many unusual variables that the usual rules don't apply.
I say this despite having zero clue what's going on here. We do have a nose for what the HN community might find interesting (we'd bloody well better after doing this job for so long), so let's override the flags and see what happens.
But without relitigating WWII please.
I didnt flag the article, but anecdotally, I was initially unable to load the article at all. It mentions how it ended up in an adblock list. The article makes it sound like this is a good thing, as it stops the DDOS, but it isn't preventing people from loading the page directly. That may be true for people using an adblocking extension, but my adblocking DNS seems to be blocking it based on that same list. I had to manually tweak my dns-based adblocker to allow the domain in order to read the article.
