Actress Keira Knightley vows to never take part in the popular social networking sites, like Twitter and Facebook, because she is convinced that they dehumanize their users, reports Starpulse.com.
The star insists that she will not give into the trend like other celebrities have, including Demi Moore and Britney Spears, who keep in touch with their fans via the Web.
Knightley also says that the Web pages featuring her are nothing more than hoaxes by imposters.
