title: Unknown Url Impression
body: <p>I have a dev site running on Heroku.  I put in google analytics.  It was working fine.  I decided to create a new tracking code so I could wipe out any previous data and start fresh. </p>
  
  <p>I put in the new tracking code in my code, then pushed to Heroku.  I noticed I was getting hits.  But it was some weird url, looks like spam but what is this /www1.free-share-buttons.top ?  why in the world is that getting logged?</p>
