An incorporate for free website seems like one really nasty way to commit identify fraud. You get the complete identity information of people who probably have a good amount of money to milk. (What type of people incorporate, but then again what kind of people would use a free version?)
Not sure if you've ever incorporated. I have, a couple times. In most states, your info goes into the state database that is wide open to the public, so you don't really get any privacy anyway.
