[registrars] trademark question and the FCC?

["Patricio Valdes" <valdes@parava.net>]

We got a call from a big comapny saying one of our users, domain
registration, was using copyrighted material on the website and that
according to the FCC we as the provider were also liable if we did not take
the site down.

Has anyone had any experience with this or is he right? If he is, this could
really be bad for all of us.

Any input would be appreciated.
