CurseForge wise, any abandoned mods/projects should be deleted automatically.
Any abandoned projects/mods/modpacks should be auto-deleted after a year.

How do you define abandoned? As I have a few mods that I have not updated in over a year. Not for lack of interest but simply no need to touch the mod. Since it works on the latest and is stable.

So you think all modpacks that have reached end of development but are otherwise functional and fun to play should not exist? That sounds like the most anti-fun thing ever.
