IIRC, he was caught posting under different aliases on ar15.com Including saying he was some sort of secret squirrill military officer, made up stories of US Special Forces using the LW rifles, and also posted false stories about reliability problems with his competitors (POF) products. In the end the characters were found to all be using the same IP/Computer, in Paul Leitner-Wise's office. This was followed by a company credibility meltdown, etc.
I don't remember the military identity bits, but I do remember reading his slags on POF, and thinking they were real.
Sad story really, as all reports say the product itself was good, and all the s**t/slagging/made up stories, were totally unnecessary (thus the mental health questions). The company that bears his name fired his ass.
