I did a site for my girlfriend's sister. It's a blog-like effort and users
can add comments to each entry. She didn't want users to have passwords and
now it's getting spammed. I'd like to add a CAPTCHA but I want to keep my
halo so I'm looking for a good *accessible* CAPTCHA solution, i.e. no
obfuscated characters, no sound files, screen readable.
I got temporarily excited by the idea of a honey trap (extra form field
hidden by CSS - if it's filled in, the Turing test is failed), but first off
it presents issues with certain assistive technologies and second, I noticed
that not all spammers have filled in the optional "name" field in my comment
form.
Simple maths problems - I've heard that these are being circumvented
already.
Linguistic solutions (e.g. "Peter bought some yoghurt, milk, deodorant and
cheese. What did he buy that didn't come from a dairy?") - this is
interesting because my girlfriend's Dutch and some of the people making
comments won't be able to read English / I can't write Dutch.
I thought maybe a code table where this sort of thing might go on:
"
A B C D E F G
6 5 4 8 3 1 2
A + F = ???
"
But that would be a nightmare for screen reader users and also might even
confuse sighted users.
So I'm still stuck.
Does anyone know of a decent, fully accessible solution to this?
If not, maybe we could create one between us, like a community project?!
