Hi everyone

I have been investigating this issue today for one of Calyx's clients. I
decided to do a bit of reading up on the issue of spam protection.

reCAPTCHA was the first solution that came to mind, however valid points about
accessibility issues have already been made.

What about the possibility of implementing a negative captcha? That way OPACs
remain accessible. It would also mean we don't have to deal with the false
positive detection of suggestions (as with analytical spam detection). The only
downside I can see with this would be a bruteforce tool that tries ignoring
particular fields or a custom coded spam bot (which seems very unlikely
considering the value of the target).

I also like the http://visualcaptcha.net/ project.



Chris
