I'm not entirely surprised. I always thought some of his posts should have had some sort of disclaimer like they use on movies. "Inspired by actual events" or something like that. I just assumed there was quite a bit of embellishment for entertainment purposes. There isn't a much Doug could do to have prevented this, I think people just have to take what they read with a grain of salt, regardless of how many posts the person has or if they're a moderator or not.
Hey, it's the internet, half the people on it are Navy Seals/Special Forces, but somehow find the time to spend most of their day arguing on online forums. You just have to remember the old saying, "Don't believe anything you hear, and only half of what you see". When it comes to forums, I'd guess 95% of it is regurgitated information taken from other online forums or old wives tales.
