Ed,
Many of these sites are putting in a captia, which is a distorted picture of
random characters. The purpose is to keep automatic spammer bots from
subscribing to the service and either mining e-mail address from lists that
the website hosts, or tying up its mailserver with junk e-mail.
Since you need to be sighted to see this garbled picture and enter it into
the appropriate box, a captia is inaccessible to those of us with screen
readers.
One work around is an audio link. You press this, and it will read a series
of characters that you must enter. The audio itself is somewhat distorted
so that a person may need to listen with headphones. Again, the distortion
is added to inhibit voice or speech recognition being used by the nasties
(read spammers).
Again, not a perfect solution, but workable for all except the deaf-blind.
Steve, K8SP
