“If a contiguous loop of non-white pixels of the same colour (the “Border Colour”) encircle at least one white pixel, and also encircle the words DO NOT ERASE written in the Border Colour, but do not encircle another contiguous loop of non-white pixels of the Border Colour, then no pixels which are both inside that loop and which are not part of the same contiguous monochromatic region as the loop may be altered.” The letter “o” in DO and NOT comprise contiguous loops of the border colours; therefore none of the existing loops are safe barriers by this definition. I therefore vandalised all of it.
