Hotmail Spam Filter problems

It's been a month now and I do not see this anywhere on the Media. My Hotmail Spam filter now seems to think that anything with the word "Pharmacy", "Viagra", "Rx" are not Spam messages.
In 2 days I got 8 Spam messages. That's incredible. I'm getting more and more as time goes, and I may have to, again, shut down an account.
What's up with Spam Filters? What's up with Spammers? Do people really read Spam?
