I read it through as well. How does Nick know what evidence the PL doesn't have? If Nick knows some damning evidence exists, why doesn't he tell the PL about it?
He seems a bit of a fantasist, and for a journalist, he isn't very good with his spelling.
The video shows the Magic Hat guy and Harris held online chats at 1am, 9pm, and 2:30am over various days. Harris is known to go online at these unearthly hours. If the Magic Hat guy is in America, the equivalent times in the UK are 6am, 2am and 7:30am. It is very strange that the two of them should be simultaneously online at 1am (Hat) and 6am (Harris), 9pm (Hat) and 2am (Harris), 2:30am (Hat) and 7:30am (Harris). (The second chat is not inconceivable). It is very unlikely that two people in the the same time zone are simultaneously online at 1am and 2:30am inside a period of just a few days. It is more credible that one person is the author of both conversations.
