You are right about social media and its ability to fuel malicious rumours. Harry and Meghan will know all about it because, just like the William affair story made its way here, the stories about surrogates, fake pregnancies and moon bumps etc that start on social media often make their way here. I find those stories much more damaging than whether William had an affair because they affect small children, who are lampooned daily, their features scrutinised, called fake babies etc. Entire You Tube careers have been built around these conspiracy theories.
And it doesn't help that UK journalists like Angela Levin have retweeted some of this wackiness.
I imagine this is part of why Harry is one of the Aspen Institute Commissioners on Disinformation. Disinformation is a global problem, and the reach of social media makes it more than a one nation issue.
You may be interested in reading Peter Pomeranstev's brilliant work on the subject, particularly if you are interested in social media, fake news, and how they are affecting democracy.
That said, the traditional UK media is still a problem for celebrities and the royal family, in how they gather and have gathered stories. There was a famous incident involving George a few years ago where he was followed in a park and Williams office had to issue a statement.
These cases are important to stop any further backsliding ...
