Better Captcha for the Drupal developer portal?

Google Cloud Apigee
1

The Apigee developer portal comes with both Captcha Captcha and ReCaptcha provided to help prevent automated registration. However, on our portal, we now see that scripts and bots can easily defeat the captchas provided by the Captcha module, and we can’t use ReCaptcha because the Google service behind it is not supported in China. We use some other mechanisms to help mitigate bot traffic, but it would be better to start with a captcha that’s widely effective.

The possible alternatives I’ve seen so far are

  • Image Recognition Captcha - seems hard to set up (especially the image licensing) and easy to for a dedicated hacker to script
  • Securimage - maybe this one? Seems to not be used much

Do you have any suggested alternatives to the provided Captcha modules?

@tpearson ,

You can try mollom / honeypot which is very effective in preventing spam. Also take a look at list here that shows list of spam preventing modules available in Drupal CMS.

Hope it helps.

We’ve deployed honeypot, botcha, block disposable email as well as some custom logic and the built in flood control modules. It’s not enough :confused:

Thanks for the list though… are there any captchas in particular you’d recommend?
