Yeah, if you get any kind of traffic at all, and some script kiddie discovers that they can fill your disk quota with fake accounts, they will. I recommend reCAPTCHA (http://recaptcha.net/whyrecaptcha.html), since it's free and easy.

Are kids nowadays so bored that they would fill up a disk quota with fake accounts just for shits and giggles?

I stand corrected while simultaneously betraying my age.

LOL, I guess.

Seconding the reCAPTCHA recommendation - I can't think of a way to make it any simpler than this. It even works if you're developing from localhost.

I put off implementing our captcha for a long time, believing that it would take a day of research, implmentation, testing, debugging; with reCAPTCHA and ambethia's Rails plugin (http://github.com/ambethia/recaptcha/tree/master), it took less than half an hour.

I'm thirding recaptcha, only because most people who roll their own captcha solution somehow forget that there are some people out there who can't read or see captchas for whatever reason. Meanwhile, recaptcha takes care of most problems with reloads and audio captchas.
