The worst ones seem to be the stupid 'pick the images with vehicles in them' ones. I'm not sure if you've run into them...
But really?? I fail 80% of the time, and I'm pretty sure that an AI would be more capable at that than me anyway... I mean look at Google photos or Facebook...
Hah yeah , I have seen those. I'm getting cars , street signs , and store fronts mostly (now that I think about it , that's the only ones I've been getting). Lately it's been absolutely horrible , it literally never lets me pass the first time anymore.
I'm starting to think whatever runs ReCaptcha doesn't know what the images and/or the correct answers are anymore.
What I don't get, is how is it still relevant? Computers have proven to be amazing at image detection and can probably identify those cars or street signs both faster and more accurately than a person...
