Seriously? This guy spent far too many words wasted speculating about something that is transparently obvious. https://github.com/malware speaks for itself. The Github rep should have said - "Dude, name yourself malware and you're surprised stuff like this happens? Try changing your name to NULL and see how that works out for you."

https://github.com/null is a user.

I'm not sure I understand your comment. I could not find github's username blacklist, so I don't think it's "transparently obvious", but if there is a blacklist feel free to share it.
