There are user friendly and secure CAPTCHAs out there if implemented correctly. A particular gaming forum uses game covers and asks users to select the correct title. This is quick enough to decipher for a human, while any OCR bots would have a difficult time with it. They could build a database of all covers, but it would be difficult to keep it up to date, and site owners could simply add more variation, so I doubt any bot authors bother to do so.
