PENALITY: (art. 17) A strike shall be called on the batter if a member of the offense intentionally removes the line and a ball awarded to the batter if a member of the defense intentionally erases a line. A team warning shall be issued, with the next offense resulting in a strike/ball, the offender and the head coach being restricted to the dugout.
Also, I don't believe whether someone tried to avoid getting hit by the pitch is protestable. (oops, not a word.)
