Old Posts Showing Up Like New

Just commented on a BP post in nutrition because it showed up on the first page and said something about 8 hours ago like that was the last post.

After I replied it says 2 years later.

Does nobody actually post in there so front page has really old posts or is there something im not understanding here?

This is on chrome on Android. I’m just not trying to reply to really old shit but it’s presented to me like it’s not.

I get that I can look more carefully at the dates when im reading through the post. Im just trying to understand what’s going on here.

I’ve noticed this also
