title: How to delete from MongoDB with conditional from another collection?
body: <p>I have two collections on my MongoDB.
  Let say:
  accounts, users</p>
  
  <p>I want to delete all the users that was last updated 10 months ago where the account is not active anymore.</p>
  
  <p>Into my users collection I have an accountId attribute, that related to the account.</p>
  
  <p>Is it possible to create a query to delete the users with the requirements? Or what's the best approach for this case?</p>
