Yep, if you open any subreddit (not including the reddit.com front page), it sprinkles days old posts in with the default “Best” filter. It’s a mystifyingly annoying change because from a user perspective you have to re-read the same post multiple times each week, and there’s no point further commenting on those threads because no one else is still engaging with them.

It’s like the worst of all worlds combination of old forums and old Reddit, because old threads keep getting necro-ed, but users have no control over which ones are coming back or when they do.
