Classifieds website Craigslist will be seeing their revenue increase 22%. One of the reasons for the substantial revenue increase is because of ads used for illegal ends according to The New York Times. These ads are expected to bring in about $36 million this year according to a projection. The projections were provided by The Advanced Interactive Media Group (AIM). The estimate was based on the number of sex ads counter on Craigslist over the month of February and the fees associated with them. Each sex ad costs $10 initially and $5 for re-posts.
