Billboard likely reported shipments, since they don't handle WW sales. That number probably came from the label.
Using mediatraffic is only fair. It may be inaccurate, but it uses the same methodology for all artists, so it's hard to claim its not fair. The only other fair method would be to compare all the certified/announced sales in individual countries.
