(Newser) – Like it or not, spam has made a comeback. Unwanted junk email is back up to 94% of all traffic, according to Google’s anti-spam Postini division. Spammers suffered a setback in November, when web backbone providers banned McColo Corp., a server spammers used to coordinate attacks, the New York Times reminds.

“By far, it was the most dramatic event we have ever seen,” said Postini’s marketing manager.
