Yeah the most recent version of CAPTCHA is completely seamless for the end user because there is no more value to be had gathering this kind of data. Instead it runs in the background of the web site, looking at your mouse movements/clicks/keystrokes, and determining whether or not you’re a bot based on that information.

The problem is a lot of websites still use the old version, or their own hacked together CAPTCHA alternative, which decent bots have been able to beat for a while now.
