+1 on this. we're starting to have the same issue at www.openpario.net

It is better to help the interactive questions, such as "how many days this month."

CAPTCHA is one of the darkest sides of the WWW. Human users should never have to prove they're not robots. I like the idea of "inverse captcha", or "negative captcha", i.e. you put in the form a trap for spambots, hidden with css or javascript, and/or obfuscate just a bit fields for humans. Until a spammer looks specifically at your website, it does the job, I use it on some blogs I manage and have nearly no spam for years.

The idea of interactive question is just a bit better than CAPTCHA, but it's still annoying for the user imho.

Please, don't introduce such a thing into Redmine...

Jean-Baptiste, if those techniques worked as well as CAPTCHA more people would use them. The main problem is the most of them fail if a human looks at the site once, and then updates their registration bot to "behave correctly".

I'd also mention that CAPTCHA can easily be made an optional feature. But not having it at all will likely be a show-stopper for some.

It could be completed, made more complicated so that it has no impact on user experience and it's still efficient. I understand your point, but I disagree with the "not widely used => not working". This is the reason why Rails doesn't enter many enterprises, and J2EE survives.

Anyway, I was thinking of a default feature. If it's optional and turned off by default, why not... Maybe it could also be implemented as a plugin, see #1131 for that, which will be integrated in the next 1.0 release.

Another useful functionality would be to check user name and mail address against stopforumspam.com

+1 for a plugin. I also was having spam problems on my site, it reached several per day, so I hacked into the sources a "Enter 'foo' here" text field. I realize a human could easily hardcode around this, but the reality is most of the spam doesn't have a human involved at any point in the process. I've had only one get through since.

To me Captchas on websites are like the Police, the Firefighters or Hospitals on the real world. It would be very nice if they were not needed. But the reality is that they are needed.

This plugin adds a reCAPTCHA to the user self registration...
