I remember when they did that book about keeping safe online, they did it when snapchat changed their settings and people could see the location of all the people they were following. People wanted the setting changed so that it didn't not automatically allow your location to be seen when a snapchat account was set up. She did a few interviews and got Maddie to talk about social media. This when Kaye was in all the youtube videos, Kaye was also in all this youtube set up to promote the two books together, I think Mark had alight bulb moment that instead of Kaye being involved it should be him instead.
Mark's a cameraman apparently, as well as sooo many other things, but look at the camera work...swaying all over the place.
