It's been taking place over the last month. A workaround was incognito on browsers, till they blocked that. Then it was switching location through VPN, till they blocked that. Then it was going through TOR which they also ended up blocking and prompting the login/signup screen as with the previous workarounds.

This is all so that in a few months time they can say that demand for old.reddit.com has dropped so they'll no longer be supporting it and force everyone to use that horrible tiktok style layout, controlling every pixel of a users device and deciding what they see.

What a downhill ride this has been.
