Moderators added at the end of old threads that this is an old thread and you might want to refrain from replying. It’s a new thing. They just added it. It might help.

Sometimes people say that replies to old threads might still be useful. Sure, if it’s a generic discussion.

Not if it’s specific question. Like if someone asked for advice about their divorce fifteen years ago, how is it helpful to advise them years later when they married someone else already ten years ago. It’s irrelevant. Or if I asked advice about my kids’ school and someone replied 10 years later when my kids are long adults and have their own children. How is that helpful?

People look for old threads for whatever reason and it’s fine. Just no need to reply
