1. Selling merit is a service, a black market service maybe but still a service.
2. This thread is discussing said service as to how to send reports against the services in question is it not?
I don't think that's a great idea. At the least, Jet Cash would be used to be an intermediate between arguments. At the most, he would be redded by dt or other members who disapprove of that. It is not his responsibility to post these, it's the users who notice it. And if he gets a lot of reports, it's not like he can go through them all and verify whether they are merit farming or not.
