if a user is active compared to a blog.- Only delete blogs, not delete user
I would want to mass delete users and blogs. I have tons of users who have only 1 blog and a couple of posts.
If an user has some blogs, what will we do?
That is why it would be good to track if a user is being active, not just blog. If a user is not active then most likely all their blogs are inactive so they both would be deleted.
List all blogs which: last post in 1 week, month, quarter, year?
I would say last post in a month. But of course, I have a policy if a blog is not active over 30 days then it can be deleted without notice (even though I give notice)
List all blogs which: total posts < 2, 5, 10, 50?
I would say two posts. This would catch 90% of the inactive blogs. There would be grace for those who have only a few posts.
List all users which: last login in 1 week, month, quarter, year?
I would say 1 month, again because of y policy.
Whatever options are finally chosen for the above, it would be nice if we could see a list of all users or blogs that are going to be deleted and override a deletion of a specific blog if desired. This is probably more involved than what the plugin would do, but a suggestion.
