"Ryan Calo writes in Forbes that Bollaert may be protected from some charges because though he facilitated the transaction, he didn't upload photos himself:
There is indeed a federal law known as Section 230 of the Communications Decency Act that immunizes websites for what users post there. So, for instance, when Sheriff Thomas Dart of Cook County, Illinois sought to bring criminal charges against Craigslist for prostitution allegedly taking place within Craigslist’s “erotic services” section, the website argued that it cannot be charged with the crimes of its users... The court in Dart v. Craigslist, Inc. invoked Section 230 and dismissed the lawsuit."
