Section 230: Protection for Online Service Providers
In Section 230(c) of the Communications Decency Act of 1996 (“CDA”), codified at 47 U.S.C. § 230, Congress made clear that “interactive computer services” should not be held liable as “publishers or speakers” of content posted by third parties. That Section provides:
TREATMENT OF PUBLISHER OR SPEAKER. 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.
47 U.S.C. § 230(c)(1), and that:
No cause of action may be brought and no liability may be imposed under any State or local law that is inconsistent with this section.
