BreOl72: My best guess is that these users
(aka: users who necro a thread accidentally) come to the "General discussion" and then click on the last page shown on top of the GD main screen, because they expect the newest threads to be found at that position.
But, of course: as the rest of us know - the newest threads can be found at the first page.
Hmm, that
does unfortunately track, but then you have the oddball threads from 2018 or so, which wouldn't fall in that logic.
It's also why I wish GOG would implement a stronger version of Barefoot Essentials idiot bar, perhaps even going so far as to gently remind users before confirming their post that, "You are about to post in a very old thread. (395 days since last post) Proceed?"
