Good morning Jim and the list,
Hi, I have seen a few posters on here with visual impairments.
I'm one of them. Blind and administrating two drupal sites.
I would like to use some sort of spam prevention on my Drupal 7 site and would like to know what has worked best for you?
I didn't have to set-up any spam protection on the drupal sites I amadministrating, so far. But as a user, what I find the mostconvenient is when sites send you a code or a link in an e-mailyou then have to re-send to the site to prove your request is legitimate.
I realise this is not an absolute protection, but perhaps this would be enough to discourage spammers: wouldthey really want to automate such a thing: fill a form, wait for an e-mail, extract the information from that mail and then re-submit to the site...
The other point is that I don't know whether there are Drupal modules to do that.
I'm currently sifting through the spam prevention modules now trying to decide on the one I will be using for the contact form.
Well sometimes captchas may be okay if there is an audio equivalent and if the sound is distinct enough to be heard. I already experienced with audio captchas youcould absolutely not hear !
A satisfactory solution for me was the one used on project Euler's website. It was audible, didn't use any javascript, so I found it pretty cool and it is the only good experience I can think of regarding captchas.
hth, Sherab.
