Going by comments in the post, the required login is coming in waves, so not all people may notice immediately.
Still, as Reddit is strong-arming its way across, maybe worth signaling to people there that the fediverse may be used without an account, so long as there’s even one instance that implements logged-out view as the protocol allows it?
I don’t have access to my account any longer, possibly VPN ban, though I never tried to recover it so I can only guess why mine is lost, else I’d post myself.
As far as I’m aware, Redlib gets around blocks in two ways. The partially implemented client-side blocks I presume are by just stripping the code (e.g. seeing the post but it’s greyed out and has a popup saying “sign in” in front of it, or when your whole screen is a login page but all the actual content was already loaded in the background, deleting that code means you can read the post just fine)
And the rest is just tricking Reddit by mimicking the request format & behavior of the Android Reddit app, which tricks Reddit into believing the user is supposed to be allowed access or shouldn’t be rate limited, because obviously anybody using the app is a real signed-in user… I guess? (this information is from their GitHub page’s README but I’m not sure exactly how all this works under the hood)
