Seriously though, although only 4 or 5 people have commented so far, the fact that you are getting a response this strong must mean you are doing something wrong. If you want, you can wait for more feedback, but the "Its ok if we abuse our customers, we have plenty of others" is sort of the paypal mentality. And if you don't have 132 Million customers, that is going to bite you pretty quickly. Assuming it is within your rights to post his info, its still a very bad move, that I'd be willing to bet will negatively effect your business in terms of new customers and your current "happy" customers.

I'm pretty pissed off still about your lack of professionalism, and I'm not even one of your customers. I can't imagine how "happy" your customers will see when they see this.
