I find this kind of funny. F*ceBo*ok is asserting the rights to its trademarked words in there Statement of Rights and Responsibilities, http://arstechnica.com/tech-policy/news/2012/03/facebook-asserts-trademark-on-word-book-in-new-user-agreement.ars. That means people of F*ceBo*k will me asked to not to used F*cebo*k’s Trademarked words. That means F*cebo*k uses will be asked to not use some of the following words: f*ce, bo*k, p*ke (that’s and O), w*ll (that’s an A), and l*ke (that’s an i).
Gotta say, Good luck!
