“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).
“This legal and policy framework has allowed for YouTube and Vimeo users to upload their own videos, Amazon and Yelp to offer countless user reviews, craigslist to host classified ads, and Facebook and Twitter to offer social networking to hundreds of millions of Internet users. Given the sheer size of user-generated websites (for example, Facebook alone has more than 1 billion users, and YouTube users upload 100 hours of video every minute), it would be infeasible for online intermediaries to prevent objectionable content from cropping up on their site. Rather than face potential liability for their users’ actions, most would likely not host any user content at all or would need to protect themselves by being actively engaged in censoring what we say, what we see, and what we do online. In short, CDA 230 is perhaps the most influential law to protect the kind of innovation that has allowed the Internet to thrive since 1996. [LINK]
CDA 230 also offers its legal shield to bloggers who act as intermediaries by hosting comments on their blogs. Under the law, bloggers are not liable for comments left by readers, the work of guest bloggers, tips sent via email, or information received through RSS feeds. This legal protection can still hold even if a blogger is aware of the objectionable content or makes editorial judgments. [LINK] “
That all being said, don’t forget to read the Comment Policy, which is linked various times all over this blog, including right before you post your comment.
