Hmmm. Excellent points to consider. Thanks. Sorry I couldn't find this link earlier.
But how do you get around the typical username/password authentication to log into one of your accounts somewhere? Wouldn't they need to be ADA compliant also? Or does a good text-to-speech reader read the text and prompt the individual to type their info?

Exactly. If it's text, it can be read. If it's an image without an ALT tag, it's just a blobbish thingy and therefore unavailable to the reader.

I have been seing services adopting the practice of offering sound files as a verification vehicle for those who can't see the image.
I don't know of a CPAN module that implements this so far, though, so you'd have to roll your own on this one.

It's a pretty effective technique, but I've seen reports (sorry, can't find any links right now!) of insidious spammers putting up fake pr0n sites with "verification" pages that are actually stolen from sites they want to spam; they are in effect exploiting visitors they attract to their site for a sort of proxy computation. | [reply] [Watch: Dir/Any] |
