I've just received this pm from a newbie. I have no intention of selling my account, and I'm not sure if I should report the user. What is the current attitude towards selling accounts? especially if the account is for a merit source. I've given him a negative trust entry. Should I do anything else?
I think you already got the answer you wanted. Since they mentioned a company, I think they would put your reputation at stake and get quick attention from the community. If a reputable guy represents a service, it would be easier for the business to gain trust quickly. Also, there is a possibility that the account buyers would use your reputation to scam people.
You did a good job by tagging the account. Even if someone doesn't have a bad intention, account selling should always remain forbidden here, and I think the majority of us share this idea.
