Bulk delete users by email address?
 

I just took over a forum where the previous owner did not bother to delete spam accounts and am trying to clean it up. I tried to use the Prune tool but the long list of results crashes my browser. I can search for email addresses that match my criteria (for instance, I found over 1,000 spammers from a .cn domain alone) but each has to be deleted individually. Is there any way to speed this up, or at least paginate the Prune tool results?
