i think people who hack for a purpose, like with a moral objective, or to make fun of opressive higher-powers are awesome, i respect them. i dotn respect hackers who just do things to vandalise and get a kick out of ruining someone's innocent life and if i ever met someone who wrote spyware and advertising software.. i would do all i could to fuck them up. i dunno if id fight em (though they ARE computer nerds often) but i sure would make a point of saying 'fuck you' in a way that sticks.
Spyware is a pain in the Ass... But it also a fun game of cat and mouse sometimes.. To see If i can kick its ass off my computer (i haven't lost yet... I've had some good fights thought)
