I mostly use one single address, but I can tell you exactly where all the spam comes from: idiots whose name is the same as mine.
They give my address as if it belonged to them. Probably they created addresses like narag33@server and they believe that it's narag@server instead.
So not only I receive all the spam from dubious sites that they suscribed to, but also their legitimate mail from lists and friends.
My namesakes are idiots. But some of the companies responsible of the subscriptions, like Paypal, are assholes. They allow the creation of accounts without verifying the email, then refuse to admit it's their problem and do something about it.
