Message on statistics for spam blacklists

This recent message about spam blacklists struck me as much food for thought (note the ratio):

So do I. I was a bit wary of it at first due to all the bashing it took, but I haven't seen any gross lossage due to it. Our current spamload is hovering at just under 300 spams per person per day. Spamcop nailed 250 of them. If there are any false positive spamcop hits in there, they are totally lost in the noise.

summary from Fri Feb 21 10:00:26 2003 to Sun Feb 23 10:57:04 2003 (2.0 days)
total spam msgs: 1170
total good msgs: 502

total spam/day: 573.7
total spam/month: 17211
spam ratio: 69%
