Daer Mr. Sanello, HubPages is a private enterprise and how they conduct their business is entirely up to them and in a private setting such as this there is no free speech if it does adhere to the site's TOS. I had enjoyed a few of your articles and I believe that HP benefited from your participation, however, I also respect their ability to make any decisions regarding their site as it is well within their rights as a private independent publishing platform.
Sorry to tell you this, Daniel, but you have no more right to paint graffiti on the side of my car and call it free speech than you do to post whatever you want on the private web site owned by HubPages.
If you don't want to follow the rules start your own site. It's that simple.
