That is irrelevant at this point.
They established clearly their purpose for registering RonPaul.com was in relation to Ron Paul the world famous politician.
Running a fan site on RonPaul.com probably would have been fine. They should have just continued doing that or shut the fan site down if they tired of it.
But now the issue is that they tried to sell RonPaul.com to Ron Paul after establishing the use of the domain in connection to RP. That is cyber squatting and is illegal. It's not about the content on the website, it is about the domain name itself.
