That change helped reduce scraping and automated abuse, but still allowed any logged-in account to access Old Reddit, including accounts with no prior Old Reddit use.

How horrible, ANY logged-in account can just access old reddit?? That needs to be fixed asap, how dare new users just use old reddit when they have a perfectly good shreddit available to them. — Reddit admins apparently

Nice admission there. Didn’t expect them to be this open about their true feelings on the matter.
