I found this site today called projecthoneypot.org and I think it's very interesting.The idea is to find and collect information about spam and where it comes from.Everyone can participate and is free.For example take a look at top 25 harvesters.Or if you have a blog you would like to know top comment spammers.And here are the top comment spammer countries.And guess who is number one?You are right!And the list goes on,top comment spamvertized domains.
Last but not least the top spamvertized URLs.
