That domain must have been pricy, even during the dot-com bust.
For anyone who doesn't want to park inactive domains, you can just remove a domain's nameservers, and users will just get a DNS error. (NXDOMAIN)
A workaround for this is to make *.example.com a CNAME for something.invalid. ".invalid" is a reserved TLD guaranteed not to exist so this should force all queries for non-existent domains to come back with NXDOMAIN.
