Why Can't We Stop Spammers?

With spam making up as much as 80 percent of all email, what is being done to stop it, and why does it persist?

This was the topic of a recent piece on NPR's Talk of the Nation, which explored the state of spam today.

On the show, which you can listen to online, guests discussed why spam is so pervasive (those new to the Internet may not know not to open it); what you can do about it (always scan for spyware); who tends to be a target (small businesses often lag behind large enterprises in tackling the problem); and the future of spam.
