So I've heard about people doing this. Happened to my friend actually. They advertise about selling TB and quoted him on a deal for his TB. He payed via paypal. After paying he received an email saying that he needed to pay more. He wondered why and refused. The website then sent him this email: The money we have received from you will go to promoting academic integrity. We are in the process of shutting down all of these illegal businesses. This is a warning. Do not use these services. We will shut down all of these illegal businesses and hold them accountable for their actions. We do not sell IM or TB. We only provide consulting to our customers that they should not be using TB or IM because it is against academic integrity and it is cheating. The amount was received for consulting service. Please, be advised that you should not be buying IM or TB. This is a warning. Promoting a fair academic environment, Wondering if you can get away with that because if you report to paypal they won't do anything since online products sent via email aren't really buyer protected.
