Interesting Anti-Spam technique

[RawAlex]

yeah, but here is the problem:

People opt in to a valid email list, say about quilting. That list is automated. There is no way for a person who WANTS to get this mail to recieve it, because the automated system will not process the "challenge".

Conversely, I could see spammers hiring a bunch of people to process bounces and get authorized, which would defeat the system. Just route all the challenge requests to some low cost providing nation, and have people paid a couple of cents per "fixed" email.

The spam will go on, the valid double opt-in lists will get blown off.

dum-dums.
