But lately a ray of light has cut through all the gloom. Spam -- the Internet's original sin -- dropped for the first time ever at the end of 2010. In September, Cisco System's IronPort group was tracking 300 billion spam messages per day. By April, the volume had shrunk to 34 billion per day, a remarkable decline. "The largest spam-sending botnets are being shut down and a lot of the big pharmaceutical spam has disappeared," said Nilesh Bhandari, a product manager with Cisco.
Everybody using spam filters and increasingly aggressive moves against the large botnets has turned things against the spammers. The effort required to outwit the filters means it's now too hard and expensive for the small scale spammers. At the other end, the big botnets have come under attack, cutting into that end of the market. It isn't going away entirely of course, but for the moment it seems the glory days of the spammers is past.
