I usually roll my eyes at these complaints, but in this case it's really quite something. I just let the page sit unused for 5min and it downloaded 165MB. Safari has much better defaults when it comes to such behaviour by ad networks: It blocks 165 requests and shows no further activity after loading 5MB: "Blocked a frame with origin "http://www.anandtech.com" http://www.anandtech.com" from accessing a frame with origin "http://pixel.mathtag.com" http://pixel.mathtag.com". Protocols, domains, and ports must match."
