Some poor lady reviewed his book and gave it 2-stars, the review laid dormant for months and one day, out of nowhere, 70 people gave it an "unhelpful" mark. That defies all logic and statistics and hints at massive coordination. When she edited her review to acknowledge the astroturfing, they came out in droves and started calling her names. Gary himself was civil, but the guy has a knack for getting all critics to talk to him on the phone so he can "fix" any misunderstandings.

Read it for yourself. It left a bad taste in my mouth anyway.
