For the record, I disagree with some parts of the analysis. In this case, Craigslist was more than a common carrier: it created a special section just for adult advertisements and charged money only for those advertisements. You could post a couch for sale for free, but you had to pay Craigslist if you wanted to post in the "Adult Services" section. The decision to charge for ads for that category intertwined Craigslist into profiting directly and intentionally from those ads.
