Hi Ashley, Thanks for considering this!
I found this project:
github.com/actions/stale
If I understand correctly, by setting days-before-stale=365 and ignore-updates=true, all issues would be unconditionally marked as stale after a year. And it’s possible to auto-close stale issues as well.
However, I'm still unclear about your approach to popular suggestions with lots of votes. Are you reviewing them regularly throughout the year, or only before the annual purge/archiving in January? What should people do if their idea has received lots of votes but ends up being closed after a year without any feedback from you?
