I've seen it before. In fact, I'd double checked last time I brought it up and it was there on /login in an incognito tab.

Either HN has changed or they now conditionally load it. For example, I encountered it every time I used Tor on HN, though I haven't hit /login in months.

I only login through Tor and I never encounter it.

Perhaps it's Cloudflare, and not HN directly.
