I’m wondering if our policy on “invalid users” (specifically new registrations that are obviously not customers) should be to delete them instead of banning them.
Banned users can still appear in some of the new user search functions.
The only downside I know of to “deleting” such users is that any posts they make become “Guest” posts. Since we don’t allow Guest posts, we should delete any posts that come from these users anyway. I believe it’s possible to search for all posts by Guest users.
