Wong ing WebpageFX Mingguan have put together quite the infographic explaining the environmental cost of SPAM. I've written before about SPAM lan industri email… Lan aku isih gumun yen ora ana wong sing maju nglawan SPAM.
If ISPs like Google, Yahoo! and Microsoft truly wanted to rid theirselves of SPAM, they would offer protected email addresses where the ISP (Internet Service Provider) controlled the opt-in methodology rather than the ESP (Email Service Provider). This would allow them to block any other source. But alas… we're stuck with a 20 year old system that doesn't appear to be improving anytime soon.
