The simplicity of it is logic defying. It used to be that you had to find crosswalks or move puzzle pieces or type blurred letters and numbers, but NOW all the sudden I can just click a box and HEY!, I’m human?
That’s hardly the Turing Test I’d expected.
By clicking the box you agree to the terms and conditions which gives them permission to use all the data they have about you to decide whether you’re human. That and mouse movement probably.
