Sv: Re: [anti-abuse-wg] how to detect spambots - SPAMTrusted

Hi guys,

Sorry, but I don't understand what kind of discussion is going on.
What do I have to do with it and why am I getting all these mails?
Please exclude me from the mailing list!
Thanks!

Best regards,
Helmut

The detection problem has been solved years ago, agreed.  There are
multiple, working solutions.

!!!
 
And even if that doesn't happen for you due to some strange scenario,
there are tons of free, external data feeds to which you can subscribe
which provide you with high-quality data about compromised customer
PCs.

Cleaning up the PC costs between 100 and 200 EUR.  Someone needs to
absorb those costs.
 
Detection is solved, but response is still an open problem.
