I sometimes fantasize about disabling Issues for one of my more popular GitHub repos, but since I also have a disturbing number of users who find my email from early git logs and send me emails like "why didn't you respond to me on github", I keep them open in the hopes that it prevents more people from doing the same.

That being said, I'd pay good money to never have to see another person submit another "bug" report where they remove all contents from the bug template I created and just write "why doesn't X do Y. plz fix" followed by an "any updates?" comment <24 hours later.

I wouldn't say the whole thing has necessarily led to burnout, since I still enjoy working on the project, but it has led to me never logging into GitHub and turning off all notifications.
