title: MailChimp resubscribe a deleted member causes the API to return a 400 bad request
body: <p>I've encountered a problem on MailChimp v3 API where it responds with a status 400 when I try to resubcribe a member. Here's the steps to reproduce the problem:</p>
  
  <ol>
  <li>Subscribe a member to a list then <em>delete</em> that member.</li>
  <li><p>Resubscribe using the API through endpoint <a href="https://developer.mailchimp.com/documentation/mailchimp/reference/lists/members/#edit-put_lists_list_id_members_subscriber_hash" rel="noreferrer">PUT /lists/{list_id}/members/{subscriber_hash}</a> returns a status <code>400</code></p>
  
  <p>{
    'type': '<a href="http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/" rel="noreferrer">http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/</a>',
    'title': 'Forgotten Email Not Subscribed',
    'status': 400,
    'detail': 'some@email.com was permanently deleted and cannot be re-imported. The contact must re-subscribe to get back on the list.'
  }</p></li>
  </ol>
  
  <p>and the request is:</p>
  
  <pre><code>{
    email_address: 'some@email.com',
    status_if_new: 'subscribed'
  }
  </code></pre>
  
  <p>Based on the response the solution is the member must be <em>resubscribed</em> which I'm actually trying to do. Anyone encountered this problem?</p>
