After 10+ years of maintaining popular projects (e.g., https://nodemailer.com/) and going through thousands of tickets in the process, I mostly ignore the incoming issues and requests now. Is it a clear bug I didn't know about – sure, I'll take it up as soon as possible. Anything else - I'll ignore it, don't even respond anything, and the stalebot will close that ticket in 30 days unless something additional comes up (usually it does not).
No one pays me for it, so I find my responsibilities to end at the point where the software is maintained and works on every supported platform. If someone does not like that, they can always fork the project.
