I installed XF 1.4 B3 tonight to one of my sites and realized that the /find-new/profile-posts was a great way of exposing some old spam accounts that I had not come across before (account was created, they post spam to their own profile posts, never come back again). Cleaning up the spam accounts was mostly easy but I ran into one issue: If the account had already been previously deleted, some had profile posts that still existed and were showing up on /find-new/profile-posts but I can't delete them. Since the account doesn't exist I can't use the 'spam' link on them. When I try the 'delete' link I get the generic "The requested member could not be found." error. When I try to select them in bulk and then delete the selected posts I get an unhandled error.
