If you could ban one person...

If you could ban one person from Zelaron and you could use whatever reason for banning them that you wanted, without worrying about it not being fair or it being against the rules to ban for, who would it be and why? Example: I would ban d3v because he's a redneck racist (He's banned already so that does not really count but you get the idea)

I would ban PENGUIN! Because penguins are featherless!!
