Negative for what? It has no interaction with anyone. No marketplace. No trust.
It's literally just for collectors or fanatics. No point in making it a fucking hassle.
Account selling is allowed but there is not a rule about giving a negative feedback for account selling. There are hundreds of cases happened like this in the past. You can check the forums if you don't believe me. Or else you can try and see. I give it like 5 minutes for it to happen from someone in the default trust list.
