I remember some time ago there was some discussion of this...
A federal judge dealt a significant victory to domain name registrar
Register.com in a lawsuit against Web hosting firm Verio Inc. over
unauthorized use of data about its customers.
In a ruling in U.S. District Court in New York City, Judge Barbara Jones
ordered Verio to stop using customer contact information housed in
Register.com's Whois database to carry out a massive telephone and e-mail
market campaign.
