Obviously there are privacy concerns. That being said, this looks like a boon for anyone interested in bot detection, as you can periodically challenge your users' humanity without getting too much in their way. Nice one, Google.
From the thread:
Implemented it successfully for a website. I have to say, it works great!
it also checks if html pages are changed at runtime and how many times you "reload" the page where the captcha is. When it thinks you are a bot a captcha popups, when entered, it got checked on googles servers if it's right and fills in a hidden input. When the user submits the form, the filled in captcha coded, again, will be verifed. [sic]

mirror, please?
Your idea started out good. Sometimes I want to research a product before I go looking for a merchant. Blocking all sites that contain ads? Just use adblock if you're that fanatical.
Why not expose it to the user? Because then they'll want to change it? Are you talking about browser fingerprinting?
We already expose this on the user/email level, where users can link and log in with as many email addresses as they like, under one account (identifier).
