And just for clarification, I'm a license holder of the top three bulk spam bot programs used in the world. Careful study of same is what led to this product, which was tested for years before release in both real-world application and also in lab-type environments such as you appear to be describing. This product is not the result of random guesswork or just throwing stuff on the wall to see what sticks, this product is the result of years of capital investment, research, development and testing that started over ten years ago. We're not playing around, we hate spam as much or more than anyone. MY personal hate for it burns with the intensity of 10,000 suns!
Our confidence in the product for what it is designed and intended to do is why the price tag and ultimately, is the very reason it is available now to the licensed xenforo market.
