Listed below are links to weblogs that reference Earthlink Spam Blocker - Visually impaired:
It looks odd at first sight but it's not as mad as you think and it certainly makes more sense than the "IF YOU CAN'T READ THIS BILL THEN CALL THIS NUMBER" that they print on electricity bills.
Blind people use screen readers to read out the text to them. So the blind person will not see the picture but will hear "Visually impaired? Click here" and can click accordingly.
Of course we'll then get some over-eager young web designer improving accessibility of the design by putting "SXMVZ" in the Alt tag!

Aha!! Never occurred to me that a machine might be reading the screen out.
Okay. I take it all back. If you're visually impaired and you're using a screen reader, it will work beautifully. On the other hand...
Martin (the author of the comment) by the way, has a cracking "End User Database" called Cardbox. Why "End User"? Because anyone can use it.

Except that I just clicked "here" (not here, on the EarthLink site), and got a 404. So that didn't work out very well.

Well, *that* was ironic (finding that you have implemented a non-accessible captcha as well). Some food for thought:
Inaccessibility of Visually-Oriented Anti-Robot Tests
Let's stop inaccessible CAPTCHAs
CAPTCHA is bad for accessibility
