I'm just fooling around, horney.
Anyway, Abba are far more important than any Captcha issue....if indeed there is much of a Captcha issue.
Seriously though, I only see this Captcha thing from a freesite submitter's side, and Viper is aiming at link list owners, which I'm not, but....
...any freesite builder that lets those codes stop a submit can't be that serious about submitting.
It looked to me like Viper had a purpose here other than simply to educate, like pushing his own script or something.
I'm happy to be wrong though.
