How I do it... (Score 0)

Having my own domain name(s), every time I sign up for a service or download, my e-mail address with that group is something like

[e-mail],
so [e-mail], [e-mail], etc. The idea here is that you'll then know just who sold you out, and since I've started doing this, I have yet to receive any spam in the past 2 years. This furthers my theory that hotmail and aol spam or sell lists of their own users.
