The username was the name of a neo-Nazi band—truly nasty stuff. That, combined with the reference to being aboriginal, looked a lot like trolling, and we got emails pointing this out. The reason why I posted such a terse comment is that, when dealing with trolls, it's important to stick to the point. If you add in anything extra, true trolls are masterful at seizing on it and making the conversation be about that instead.

However, the story has a twist. The user emailed us, and it turns out he had no idea what the username meant and was deeply shocked to find out. We've renamed the account now, and all's well. I'll check with him if it's ok to leave this answer up.
