I thought the original idea was not to do with the screenreader module as
much as a proposed ... next segment ... of events determined by the human
mind?

but it would not take creators of bulk mailing software and scripts long to
make a fake version of the screenreader module thus breaking the
verification system for themselves also.
Going back to Damon's idea, I seem to remember that Lloyds TSB used this
kind of system at one time. The problem with asking sequences of numbers or
questions is that some extra work may be required unless a random selection
of questions can be generated that could just always automatically be used.

Maybe, and I think the questions would probably have to be dynamically
updated every day or so by site administrators, rather than lying in a
database somewhere , because that approach wouldn't take bot designers very
long to get around. I do like the idea of a Screen Reader Validation
module, not least because it would make it far easier for us to access sites
and content written in other languages (paypal Spain, for example, does not
have the audio version of the visual verification). The only problem I can
see with this approach is that a major spammer might well be prepared to
spend $1000 on a screen reader, or even $100 on something like Freedom Box,
if it gives them apparently legitimate access to Hotmail, Yahoo, Pay Pal,
political votes and discussion boards etc. The only way round this I can
see would be for the SRVM to submit information about the user e.g. name and
serial number back to the Screen Reader manufacturer each time it was
accessed, and I wonder how popular that would be.
