The fact that it's the only site I've seen that demonstrates the ability to read HTTP referral headers from hacker news shows who the real hacker is...
Nah, just having a problem with the hug of death would be an explanation for redirecting to a polite static message saying "sorry, my site can't handle the load when HN links to it". What he has done instead is excessively diskish.
You must be using Brave or a browser plugin which doesn't send referral headers. If you use a normal browser, it displays a testicle in an egg cup with a silly phrase complaining about the demographic of HN users.
An incognito window doesn't quite count as "if you use a normal browser". Unless your not using incognito is the unusual case for you, which it isn't for most users.
Given a choice between changing my browsing behaviour to see his content or just blocking it so it (the testicle redirect or the other content) will never both my vision again, I go for the latter option.
