Indeed as accessibility enthusiasts we are not in favor of CAPTCHA. I
too was thinking the same thoughts as Jennison: folks from the IT
security field should be involved in this discussion because it is
necessary to get their buy-in on not using CAPTCHA or using
And it is absolutely true that businesses should not subcontract
essentially their problem of distinguishing real users from fake ones
onto visitors and must really rethink of how to manage traffic to
their websites.
It was gratifying when a major credit card company decided to do away
with their CAPTCHA on the registration form this past summer based on
our advocacy. They took some six months to evaluate their strategy and
finally decide that there were other security mechanisms in place and
CAPTCHA was unnecessary.
