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:

Can’t redlib operators just use a reddit account for? Login to get past the login wall, and then fetch requests for other users
RedLib presently spoofs the OAuth tokens and behavior of the official Android app to access the website, so they are kind of doing something like that already.
The challenge for instance operators is routing the traffic appropriately to avoid the inevitable rate limiting from Reddit for popular RedLib instances.
Instance operators end up using a variety of approaches to get around this such as having multiple RedLib instances each with its own IP so that if one becomes rate limited, their site can switch over to another instance while the rate limit cools down.
That’s a potential solution but there might be problems I haven’t considered.
Presently that’s not how it works though, redlib doesn’t log in.
