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.
Cheapest Logitech mouse I could find in the supermarket about 6-7 years ago.
As others have said, it might be more to do with my browser choice, browser settings and extensions. That said I remember when I first started seeing these years ago that sometimes it’d think I was a robot and sometimes it wouldn’t and maybe it was a placebo effect, but I felt fairly confident then that me jiggling the mouse really helped. Now it doesn’t matter what I do. My natural movement, a deliberately wonky but still single and continuous movement or a totally artificial mouse wiggle after the clock, I’ll always have to do captchas.
