Capture your customers, don't CAPTCHA them
Take a step back. What ARE you protecting? The Crown Jewels? Then crank up the CAPTCHA. A random spam comment showing up once a week on your company blog? If you're running a company blog, you're going to want to be vigilant anyway. Cleaning up some spam isn't that onerous of a job. You can also make your blog comments requiring approval before posting. The danger in this approach is the honest blog commenter is robbed of the instant gratification of seeing his/her words posted immediately. If you're trying to nurture engagement, it's a good way to snuff it out.
