Google announced that it was changing ReCaptcha to NoCaptcha or NoCaptcha ReCaptcha actually which is the same service but instead if is designed with a better algorithm to analyze whether it is a real human visiting your site and trying to fill out a form or if it is a bot. Going forward instead of seeing a ReCaptcha form if Google identifies the browser as a human visiting instead they will only have to confirm a checkbox that they are not a robot.
If the algorithm isn’t sure you will be prompted with a much larger variety of ReCaptcha options that are quick and easy for a human to select, but much harder for bots to be programmed to answer properly, these things involve seeing an image and having to match the picture to another image of something related, something incredibly hard to program a spam bot to do.
What do you think about NoCaptcha and will it help the EVER growing army of spam bots? I know I want the spammers to stop on my own forms and they seem to defeat Captcha just too easily right now.
