Also to note, he's Butters Stoch. Ban or leave him be? He's a moron but his original account isn't banned and currently un-used.
Personally I'd ban him, but I'm biased with discontent for his idiocy.
Last I checked we banned people who made puppet accounts if we didn't like them as a poster.
If he spams on his current account feel free to ban him.
No surprise there. Do whatever you want, but I'll give him three chances. Three stupid posts and I'm banning him.
