Reddit/Lemmy just leads to the same questions getting repeated again and again because it’s easier to ask again if you don’t see a discussion on the subject that interest you in the first few results.
I wonder if this just comes down to moderation strategy more than anything else.
Reddit does have post archiving, but there’s nothing otherwise stopping dead posts from being repeatedly revived. A lot of old forums would request a fresh thread as well when one got “necro bumped.”
