How Well Do You Estimate?
A random UK blogger has published a quiz asking readers to estimate various numeric values which they may or may not have knowledge of; and has analyzed the resulting answers to determine how well people guess. The first part of the results looks at some specific questions, and the second part takes a look at the quiz overall.
Since the Slashdot effect is so powerful, why doesn't Slashdot offer a section for posting full copies of spam mail, with headers.
The true source IP can be extracted and listed as a special bulletin complete with a link to said IP address. When all the slashdot readers try to connect to the trojaned server, it clogs up the pipeline for the ISP and MAYBE they will get a clue that something is wrong. Meanwhile, that's one less system spewing out mail for a while.
Or better yet, subtitute the IP address in a banner ad or graphic. That way, the calls to the trojaned servers are automatic.
