Tbh, and I plan to do this for piefed.social soon (and rimu has given me the go-ahead) - abandoned discarded communities with literally zero posts need to be purged by instances. It’s just clutter.
Cool, it’s a good idea. But there are also other instances.
Then there is the issue of communities with a large number of subs but where the last post was 7 months ago and they have 0 MAUs. While a community with a lot less subs can have several posts per week and at least some MAUs (couple of hundred).

This is how we know that the overwhelming majority of “anti woke” posturing in American society is mostly about theatrics and subservience to oligarchs.
