The best way to deal with it is to use emails such as hotmail, which have a setting that only allows emails from your contacts to reach your inbox. All the other free emails I'm aware of allow spam to get through, except that one. Not a single piece of spam, ever.

The anonymity of the web and the global nature of it makes it impossible to hold spammers accountable. The best we can do is, if we know anyone personally who visits or buys from a web site that spammed them, beat them senseless. They're the real culprits. If there were no profit margin in it, it wouldn't happen.
