Perhaps I'm the only one bothered by this, I dunno, but I don't see necroposting as contributing anything to the conversation and it seems to be happening a lot. I don't want us to appear to turn away people who have legitimate questions but wouldn't it be better to have said people create a new thread to ask something? Honestly I don't see the point of a thread being bumped merely because someone, for example, wants to ask a question to an OP who no longer posts here in a thread that had its last reply a decade and a half ago. I try my best to stay away from threads like that!
I'm not really sure if there is necessarily a clear-cut solution to this but I would like to acknowledge that it's a problem that keeps happening. What about something like locking a post after a certain number of years with no reply, is that a legitimate response? Heck I don't even know if that's possible. I will say though that I don't think I've seen one rude reply to any of these and that makes me proud of you all.
