title: How can I delete all blocked users with Drush?
body: <p>How can I delete all blocked users with Drush?  I have hundreds of blocked users from spammers.  I want to delete all these users.  I tried doing it through the web interface, but this only works for about 20 users at a time.  I have 60 pages to delete, which takes too long and is unsustainable.  Also, I want all the relevant callbacks to be run when a blocked user is deleted, and I want all its content deleted.  I noticed <code>user-cancel</code>, but this appears to only apply to a single user.  Is there a way to make this command work with all blocked users?</p>
