As I said, most of the articles on that website are absolutely spot on.
Also, I remember the 80s. There were lots and lots of stories about the problems in the Wales' marriage, Charles cheating, Diana's eating and emotional issues.
People were the same then 'Oh, it's just scurrilous rumours, all to sell papers'. Turned out that was all true too. The media do generally have good sources for their royal stories and demand a higher level of reliability before running with it.
