Please note that you will be liable for damages (including costs and attorneys' fees) if you materially misrepresent that a product or activity is infringing your copyrights. Indeed, in a recent case (please see
http://www.onlinepolicy.org/action/l...opg_v_diebold/ for more information), a company that sent an infringement notification seeking removal of online materials that were protected by the fair use doctrine was ordered to pay such costs and attorneys fees. The company agreed to pay over $100,000.
