As of a few minutes ago old.reddit.com now seems to requre logging in to access it.
Shame as it was still the best place to browse for info about some niche interests.
Edit: Seems like they might be testing the change as it is hit or miss at the moment.

||reddit.com^$header=referer:
Reddit is unusable without old reddit. Reddit.com is a horrible user experience.
Redlib still works, but it’s read-only (not a problem for me, I killed my Reddit account last year), and it’s probably a matter of time before that’s killed off too.
