Hank’s TaubmanSucks site exhaustively details the legal wranglings that ensued when he registered a domain with the same name as a mall that was under construction near him, for the purpose of posting fannish reviews of the mall once it had opened. The mall’s lawyers, halfway across the country, brought him to court for trademark infringment, and Hank defended himself, with help from advocacy groups like Public Citizen and the ACLU, and eventually prevailed. He’s detailed every step of his work from initial letter right through to judgement — it’s practically a HOWTO for defending yourself from routine trademark shakedowns.
(Thanks, Hank!)
