XF 1.5 Validating Google reCAPTCHA


Well-known member
This is googles fall back method if it is unsure if you are a bot

It will appear for some users, if they haven't triggered enough "human activity"
It generally doesn't pop up if you are signed in with google and have completed reCaptcha in the past

ReCaptcha - NoCaptcha The Inner Workings

There are no options to turn this off, and you wouldn't want too, since it appears when big G is unsure (mostly for bots, not so much for humans that have "proved their selves")
