Few days ago I’ve read an interesting article of how spammers break the CAPATCHA technique that is used widely to stop them. Apparently they use “naive” users to do so!
They would ask Internet users surfing some sites over the web to help tracking down the CAPTCHA code!
And they would use some attractive methods to motivate users, and it seems that it’s working quite well!

It’s worth mentioning here that Bruce Schneier has expected spammers to do so long time ago!
I think that such technique is much more reliable than using automated CAPTCHAs decoders!
