Check out the spam volume graph at: http://www.rhyolite.com/anti-spam/dcc/graphs/db-size?resol=1year
Granted, it's only what DCC sees in queries from spam-checking clients, but it's a pretty dramatic graph! There's a slight dip in January, possibly corresponding to the CAN-SPAM Act going into effect. But there's a much bigger drop this month. Any idea what could have caused it? A similar pattern can be seen on other distributed spam volume graphs (Message Labs, Spamcop, etc.). Pierre Thomson BIC
