Fun that people still think CAPTCHA, especially reCaptcha - which is extremely widely used - is any good against bots. I have a small personal website with a simple comment form secured by reCaptcha. One or two spam entries per week. Don't tell me some Chinese guy is being forced to solve them, because posting spam on a website without any traffic doesn't generate profits. That leaves bots solving them. Welcome the 21st century's image recognition.
