At least when people draw rude pubic pictures I get to mentally rate their artistic merit, and it sometimes shows that a lot of care is taken in creating the image. Heck, four letter swear words at least indicate the mood or feelings of the writer towards the exhibitions.
Writing SWAG!!!1!! (the 1 in there is not a typo, it's verbatim) seems rather pointless. Unless they are really indicating an overwhelmed appreciation of our impressive style and panache?
