How can I account for users' ad blocker with pinit.js

Question

I'm building a wordpress plugin that will all the user to share the current page on select social networks. The plugin reaches out to pinterest to load pinit.js, however I am running into issues when the user has an ad blocker on their browser.

Is there a way to work around this? My share functionality is still intact, it's really the styling and alignment that seems to be affected. So maybe I could set up some fall back styles in that case. I'm seeing the following error in the browser:

GET http://assets.pinterest.com/js/pinit.js net::ERR_BLOCKED_BY_CLIENT

The following script is calling for the js file and throwing the error:

<script type="text/javascript">
      (function (d) {
        var f = d.getElementsByTagName('SCRIPT')[0],
          p = d.createElement('SCRIPT');
        p.type = 'text/javascript';
        p.async = true;
        p.src = '//assets.pinterest.com/js/pinit.js';
        f.parentNode.insertBefore(p, f);
      })(document);
    </script> 
  <script>
