The Spamhaus Project, Ltd which is the go to source for many to identify and track spammers just filed a UDRP for the domain, Spamhaus.com
The Spamhaus Project, Ltd operates under the URL Spamhous.org
The domain name Spamhaus.com is owned by Ondova Limited.
You might recall that Ondova Limited is the company which Jeff Baron owns or owned who has been in litigation for many years now over the control and disposition of the company assets, including the bankruptcy court ordered sale of some great domain names which was overturned by federal court
We wrote about Jeff Baron several times including here and here
The domain name Spamhaus.com is not going to a parked page but just a “for sale” page
The domain SpamHaus.com was owned back in 2003 by Compana LLC while The Spamhaus Project registered the .org in 2003 as well.
Should be interesting if someone files a response to the complaint.
Actually, spamhaus.org was registered four years earlier in 1999.
