Ferriss openly advocates falsely claiming to be an expert on a subject, and pretty blatantly acquired fake 5-star reviews on amazon when launching his books. He also talks about e.g. gaming the weigh-in for a kickboxing tournament to compete in a category two below his natural one, and then pushing all the other competitors off the platform to abuse the TKO rule rather than doing any actual kickboxing. He does not come across as a nice guy.
