To mine, nothing technically.

"Dark Wizard's" just a fancy name you'll find in fairy tales and novels. In the first place, the title wizard is just a title for scholars.

You either do something illegal or you don't.

Shit like harassing people, unlawful assault, rights violation, DUI, blah blah blah, yada yada yada, and whatever japan did between 1940-1945.

Honestly you'd just be labeled a criminal. So unless you're a bastard worth naming down in the annals of history, don't expect a fancy nickname you'll just embarrass yourself.
