I've never understood the philosophy behind it. Why, if everyone hates it, are there people that bother to create spews of spam that don't only annoy, but have the capacity if not handled properly to bring down a company? The same with viruses that do nothing but cause denial of services (I can see a purpose behind spyware and such)...why does it happen? The energy could be so well spent somewhere else. I am astonished that companies even have the audacity to create spam; do they REALLY think that it increases marketing/profit? What is the deal?!
*edit @Phantom. I don't even use Hotmail anymore, not even for messenger. (Gaim!) Otherwise, you couldn't get me to shut up about SPAM....
