List of spam-email-address-collecting bots IPs?

[rchilakapati]

Hi there, I was wondering if anyone knows of a site that lists all known IP addresses of bots that hit sites with the purpose of collecting email addresses for spam? I operate a pay-per-click site, and have filtered out clicks from SEs and the such, but there has been concern that the number of clicks attributed to these 'email-collecting' bots isn't insignificant.

Thanks for your help!

And also they fake their user agent string to appear as if they are regular surfers. A spider [webmasterworld.com] trap [webmasterworld.com] would probably be a good solution.

Not sure if it would even be feasible to create such a list as the email extracting software is available all over the internet and used by a WIDE variety of people. Many of these people will be on dyanamic IPs so any list would end up penalizing inoocent people who ended up with the IP that someone else just used to gather email addresses.

The big-time spammers that use these will also like use a dial-up connection to avoid tripping filters and getting their true IP banned.
