You realize for recaptcha to work best you are supposed to use it on all forms and actions and background of pages?

"reCAPTCHA works best when it has the most context about interactions with your site, which comes from seeing both legitimate and abusive behavior. For this reason, we recommend including reCAPTCHA verification on forms or actions as well as in the background of pages for analytics."

When you say reCaptcha doesn't capture user data are you lying? Have you actually implemented any of this and tried to fight fraud. I ask because you and the original author are making a lot of big claims and ill intent assumptions that literally ANYONE dealing with large scale fraud attempts would see through immediately.

Seriously, everyone else is sticking all sorts of beacons on websites for this - that's currently how it is being done.
