That list is based on what we've observed recently in our data network, 
collating delivery logs from a whole bunch of ISPs and other sources.  Since 
it's aggregating multiple views, we tend to see more than a single site would.

(You can look up some data without registering, but not all.  Either way, 
it's still free.)
