Yes. The codes are normally generated randomly and made difficult for optical character recognition to decode. Some bots might still get through, but the frequency should drop quite a bit.

I had a spam problem at my site. It went away after I turned on the verification feature. Since it is a nuisance, I turned it off again after a brief period. Spam did not resume.
