> The DDoS is pretty obviously ridiculous, completely unacceptable, and entirely indefensible, while the blog post seems like whatever
The DDoS hasn't even successfully taken the website down, so your objection is entirely ideological.
It's a pretty messed up ideology if attempting to take down a website is worse than potentially subjecting someone to violence by attempting to dox them and sharing your work.
Nonsense, by the mid-aughts google searches and whois lookups were key tools for doxing. If you had been around in the hacker scene at that time, you'd be well aware instead of trying to inject fabricated mystique.
We called this exact pattern of behaviour "doxing" on IRC in the early 2000s, I really don't know why you think I'm using some new definition.
It's probable that in the later 00s this would have been called a "faildox", but it's still just a fundamentally dick move to try to identify someone online who doesn't want to be identified. It doesn't matter if you do a completely shit job at it.
