I noticed today that spammers are using their initiative to get around Yahoo mail's new 'state of the art' spam protection - Spam Guard

Normally when you open a mail there is a button that you can click stating "this is spam." However the spammers have come up with a script that changes that button to say "this is not spam." On top of that, they've also changed the language on the next page, that gives you the option to block or report the, spam to Korean.
