Spam in Q1 2009 increased 1.2% per day

Spammers have clearly rallied following the McColo takedown, and overall spam volume growth during Q1 2009 was the strongest it's been since early 2008, increasing an average of 1.2% per day. To put that number into context, the growth rate of spam volume in Q1 2008 was approximately 1% per day – which, at the time, was a record high, writes Amanda Kleha.
