AOL Spam stats
According to AOL's stats, they've blocked almost a billion bits of spam today. That's a lot of spam.
I've probably received between 30 to 40 spam messages today, all of which were blocked from hitting my inbox thanks to spamcop.net with no false positives. I've routed all my personal mail through their servers for almost two years now and it's easily worth the $30 a year I pay for the service. It makes email fun again; now if I get mail there's a very good chance it's something I want to read and not another ad for a fake Rolex (which seems to be the current big thing for spam).
