This is just so pathetisad.
I have seen this same thing play out on forum after forum. Someone asks about Alexis McGee or one of her classes or products, there are some positive and some negative comments made. Then sooner or later Alexis swoops in demanding everyone "reveal" themselves to her so she can verify she actually did business with them. Then there is the round or two between her and others that essentially reduces down to the old "I'm rubber and you're glue" playground bit.
Ms. McGee, I know nothing about your classes, courses or sites other than these types of exchanges I've read in several places. I believe you think you are defending your brand but it does not promote a flattering picture to the outside observer.
I think everyone who has any kind of web presence could learn a really good lesson from the US Air Force in response to these types of things. They have a flow chart they use to decide when and how to respond to something online about the US Air Force. Interestingly, most of the paths lead to "just monitor".
Why? Because the people running the online presence programs for the Air Force know creating a scene about something gives it far more attention than it would've otherwise received.
As with all things in life, your mileage will most definitely vary.
