I wonder if the abandonment occurred around the time that image uploads were disabled, old images wiped and instance was often down. That's about the time I realized it was basically impossible to moderate and contribute to a community I created on the instance. I now handle mod duties from another instance, one that is usually accessible and allows image uploads.
Image uploads are not disabled. There was an issue that was resolved. And if you look at the moderator for this community you see that they have been inactive for about 2 months, long before any of that.
