I enabled hotlink protection and traffic is back to normal from a 50% drop in visitors. Which is prove that google hotlinks images wasting bandwidth that we've paid for.
However with hotlink protection now when people click "view original" it redirects them to my home page which is bad for visitors.
But its clear that google is lying in the blog post that the CTR is actually higher because as it turns out out of 5 links on the new display image page 50% click the "view original" button.
