As the maintainer of a moderately popular project on GitHub I'm torn in this. I often get issues where I try to solve the user's problem and think I have answered the question or provided a solution, but don't get any reply from the reporter when asking if it is solved, sometimes for years. I configured Stale Bot with a IMO generous delay so the user has enough time to at least give a short reply if the issue persists. If it does, I'll gladly add a 'pinned' tag to keep Stale Bot away from it. But in the end the bot just does what I'd do by hand anyway.

If it's configured with a short timeout and with preventing further comments, I totally agree. That's rally annoying. But maybe there are circumstances where it's actually useful.
