There are ways to break everything. Even if we had the best security system available, we'd still run into problems.
You can temporarily slow down the spam, but you'll never be able to avoid it completely.

As far as CAPTCHAs and alternatives...I'm personally a fan of the honeypot method. Or, if you want a visible CAPTCHA, the "wasted attention" CAPTCHA, e.g. like this (though not an ad):

Since both of those are actually readable, I don't mind either.

After studying a single course in image analysis, I'd say the captcha on the right is significantly easier to break. I could probably write a program to break it myself without too much trouble.

I figure the best would be semantic questions which would be easy for a human but not for machine, e.g. "what's the opposite of small", or "what color is snow".
