David Emery, at About.com, has dug up some interesting clues about the time-travel spammer. He notes that an authentic mind warper generator was once offered for sale on eBay, as well as a Generation 4 Dimensional Warp Generator. Bidding on these items has closed. He also notes that there's speculation that the mystery spammer is a well-known, Woburn-based spammer named Robert Todino, since the mystery spammer states that he lives in the Woburn area. But someone who wrote to me claims to have talked to the time traveler on the phone and supports the theory that the guy is crazy as a loon.
