Oh wow, and here I was thinking Clavius was just being lazy with thinking of an actual example as no one would possibly be unimaginative enough to actually go for a name like that ingame, but all of a sudden it turns out that actually happened and was one of the recent sanctions (with the player behind it now playing amusingly and entertainingly albeit miserably and pathetically bitter). Well played sir, you're managing to lower a bar which none of us thought could possibly ever go any lower.
I changed my mind. Just limit everyone to firstname.lastname, cause there's no other possible solution for this issue.
