A literary agent has sued the Wikimedia Foundation and Wikipedia contributors over negative remarks, but Wikimedia argues it's not liable for user-generated content.

Barbara Bauer recently filed a lawsuit in New Jersey Superior Court claiming that the Wikimedia Foundation is liable for postings that called her one of the "Dumbest of the twenty worst" agents, who has "no documented sales at all."

Wikimedia filed for a motion to dismiss the case, saying that Section 230 of the Communications Decency Act, the First Amendment to the U.S. Constitution, and state free speech laws, gives it immunity against such lawsuits. The federal communications law states that owners and operators of interactive sites cannot be held liable for user comments.

Courts have upheld the Communications Decency Act in several cases brought against Web sites and discussion boards for user-generated content. Courts have ruled that people with complaints of defamation on Web sites should target users who make comments, not the Web sites themselves.

While many sites add user-generated content to enhance user experience, Wikipedia relies almost entirely on posts from contributors.

However, as people increasingly use the Internet to bully or defame others, policy experts and courts have been scrutinizing Web sites' responsibility to police content.

For example, the New Jersey attorney general has subpoenaed a college gossip site and begun an investigation into whether the site engages in fraud by telling users it will remove or block obscene or abusive posts.

Wikipedia has an editing process in place, which promotes neutral viewpoints and discourages personal attacks. It also allows people to dispute entries and removes postings that don't comply with its policies. The site does not currently have an entry on Bauer. A Wikipedia deletion log shows the entry was deleted in March. It was first deleted in May 2006 and has since been restored and deleted several times, according to the deletion log.
