I like this juxtaposition of CAPTCHA codes with GRAFFITI (there, we give it the same emPHAsis). Bartholl has done us a service by putting them together. CAPTCHA is about stating what we are not to a program, i.e., not a robot, as much as stating what we are, i.e., a person at the keyboard. GRAFFITI is about stating that its author is not invisible, as much as turf wars which is another way to say "I belong".
