High Quality Content by WIKIPEDIA articles! A person who is found to have published a defamatory statement may evoke a defence of innocent dissemination, which absolves him/her of liability provided that he/she had no knowledge of the defamatory nature of the statement, and that his/her failure to detect the defamatory content was not due to negligence. The defence, sometimes also known as "mechanical distributor", is of concern to Internet Service Providers because of their potential liability for defamatory material posted by their subscribers.
