My negative trust has to do with the fact that his name is very similar to another account seller who has been around for a while without major incidents (and as a result people would potentially trust enough to send bitcoin first to him).
I think it is fair to say that his username is closely sounding enough to ACCTseller that someone could potentially mistake him for it.
IMHO ACCTseller and AccountSller are very easy too differentiate on first sight.
impersonating an username works if they look similar on first sight. as ACCTseller has uppercases in front (which is unusual - means more people will remember it) they are easy to differentiate.
