A cosmetic surgeon in northern California has filed a libel and defamation lawsuit against a host of online critics who were allegedly “badmouthing” her on the Internet. Dr. Kimberly Henry claims in her lawsuit that at least 12 different online reviews have engaged in “libel and defamation, invasion of privacy and interference with prospective economic advantage” by posting “scathing reviews” on various Web sites. The lawsuit seeks $2 million in total damages.
