I am not 100% sure that he is the first one, but he for sure is the first one I know of. All my bets were on Lukarb, but someone was slowly chasing him.

Congratulations, mighty hox! Well done and well earned.
Sadly there is no rewards or title for it to show this huge accomplishment off. But maybe @AndyB can do something about it? Some cool unique badge perhaps?
