2010 Spam
Another year, another deluge of spam. This is my second year using Postini for spam filtering so while I don't have detailed statistics I can at least compare to last year. For 2010 Postini flagged 63,436 messages as spam or 45% more than last year. My incoming spam rate spiked up to 250 a day in April, May, and June before finishing the year with an average of 170 per day. A quick Google search confirms that some of the biggest dips in the graph below are tied to known spammers being shutdown.
