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.
Edit: Adding this to My flilters in uBlock Origin seems to fix the issue for the time being:
||reddit.com^$header=referer:
In five years my reddit account won’t need verification since it’s currently 13 years old!
But yeah there’s a bunch of solid info and guides on there, niche subjects. I browse some niche subs sometimes but I refuse to interact, not even up or downvote. Sometimes someone asks a question and it hurts to not be about to post the answer, but I only actively use Lemmy and forums now.
