I believe the legality is it's a punch in the throat for "couldn't care less" and a kick in the balls if you try and argue "there, their, they're".
Of course bringing up the proper use of a semicolon comes with the death penalty.
If you even bring up the word semicolon you are hung for Witchcraft. Also if you try to correct anyone for the usage of "there, their, they're" you lose a toe. We don't play round hurr.
