What I do is create a special hotmail account for my pp. When you do that, you can use it when you try to get the free subscriptions. Then it don't matter that you (might) get a lot of junkmail, because it's just one you created for the magazines

I think Maxim doesn't show any nudity, breasts and genitals are covered (just bathing suits, panties and such), so it should be alright. Playboy and penthouse are usually a no-no...
