We have implemented the signup module on our website for event registrations. All users on our website are anonymous. We are seeing a large number of spam signups for our events (i.e. more than 10 per day). Any suggestions on how to limit this? I would prefer to address this without using a CAPTCHA. For example, I understand there are some techniques with using hidden fields that often can detect spam signups.

I should have stated this in my original post, but I am willing to pay for this feature. Thanks.

Taking inspiration from http://www.isegura.es/blog/stop-spam-your-site-being-invisible-honeytrap... I've added a text field to the Signup form, hidden by CSS, and assumes that all spambots will fill out every text input field in a form. If the 'Honeypot' field is not left blank, then the Signup is rejected.

Just unzip the attachment (an incredibly small module), place somewhere in your /sites/all/modules directory and enable. No other settings necessary

Thanks Rob for sharing, and thanks also for linking to my blog.

Please notice, if you need some extra "bang" to stop those SPAMmers, I also detailed another (very simp`le) method:
