I have a Multisite installation with around 3000 subsites, for my WP Dev Udemy course Student Sandbox. It's a private network for students fo the course.
I'd like to be able to delete older, unused subsites.
Can I use Prosites or another solution to set a non-use expiration, or a time-limit after which subsites are deleted?
Or alternatively, can I monitor when subsites have had no activity fro thre months, and then delete them manually?
Thanks for your ideas!
