Google's reCAPTCHA showed street numbers as one of the two catcha-"words" for more than two years. For me this was quiet annoying to input street numbers of others. It's a privacy issue, it was like helping the NSA spying and one feels bad entering Google's captcha. What is even more astouning is that Google does not even mention all the croud sourced "volunteers" that trained their OCR database. As Google use an open OCR software (former HP OCR app from '95) it would be a good choice to publish their data back to the community. I removed Google captcha on my own sites and implemented my own traditional captcha (on the first sight of it about two years ago).
