What is the PF policy on very old unanswered threads?

[Wrichik Basu]

Just now, I stumbled upon a long list of about 198 unanswered threads. A majority of these are homework problems, posted long ago, say in 2016 or so. In many cases, the OP was last seen on the date of posting the thread, which shows that these are all useless content. Few are spam, which might have been overlooked by the mentors somehow. I have just reported some of them.

What is the PF policy on such threads? Should they be deleted? Should I go on reporting such threads?

Report the spam ones, leave the rest, thanks!

OK, got it.
