Fake guest user accounts

Is there any way to prevent false guest user accounts being created in Omeka 2.3? I am having to go in and delete pages of fake accounts.

If you have reCaptcha set up in the security settings, those should appear on the registration form. Those aren't perfect, but they're the best option we currently have.

Is there more setup required than entering the public and private key in security settings? I've done that, but reCaptcha doesn't show up on http://omeka.wustl.edu/omeka/guest-user/user/register

Go into the configuration settings for the Guest User plugin - the very last item should be a "require ReCaptcha" checkbox.

sorry, there's just the checkbox in the plugin's configuration form. that should be everything

That did it. Thanks!
