Based on other posts in that thread though, he also appears to be behind CG-NAT, which is always a confounding factor for IP-based blocking. Maybe someone else on his netblock is running that crawler.
Since that link refers to opening HN in an incognito window—and all those requests would be logged-out—most probably it was that activity that triggered the block. As I think I said elsewhere, it's hard to distinguish between a legit user accessing a bunch of HN links in various tabs, and a distributed botnet making similar handfuls of requests from a million different IP addresses.
What I can tell you for sure, though, is that the claim that we were targeting any individual user is quite false. Isn't that the main point?
Edit: there are two exceptions—accounts we blocked because they were running crawlers that didn't respect HN's robots.txt—but both have been blocked for much longer than a few days.
