Disclaimer: I?m not an attorney, I just do a lot of research on cyberlaw.
A message board owner isn?t liable for a 3rd party posting. However, you can?t encourage libel, nor can you ( the owner) post something defamatory. Exceptions to this rule are copyright violation, illegal material (underage porn pics), and privacy law compliance. If you have anything that violates those 3 things, you need to remove it ASAP. I think under the DMCA, you have to remove any copyright or IP infringements, given notice
The only good thing about the CDA (Communications Decency Act), was the immunity given to ISPs for 3rd party actions. Congress had a vested interest in promoting good behavior. Companies used to be afraid of monitoring their message boards, because of legal exposure. To address that, Congress added Section 230, which states: ? No provider or user of an interactive computer service shall be treated as the publisher or speaker of any information provided by another information content provider. ?
