Visualizing Yahoo Spam Blocking
This cool website from Yahoo shows how many emails they're processing every second. Of most interest to me is the amount of spams they're blocking: Click on the "show blocked spam" button to see for yourself. Doing some rough math this morning, it appears that right this second, only 84% of inbound mail attempts into Yahoo are unwanted spam, meaning that "only" 84 out of every 100 servers in the Yahoo inbound mail server farm are wasting their entire existence on processing mail that nobody wants. Ouch, what a waste.
