Sierra Corporate Design's 2004 website, courtesy of the Archive.org
Sierra Corporate Design is the entity suing two spam activists, who revealed that Jerry Reynolds was the largest spammer on Usenet. Sierra Corporate Design, the company, is owned by Reynolds. Both are located in North Dakota, and Jerry Reynolds was the owner of the sites, Netzilla.com and Sexzilla.com, in the mid to late 90's. These sites were the largest spammers on Usenet.
Tomorrow, one of these guys being sued has to turn over computers and faces a court appearance in North Dakota (he lives in CA). Therefore the North Dakota court has no jurisdiction over him.
