A reCAPTCHA is supposed to make business tough for bots yet easy for humans to decipher. But we all know how annoying those things can be – for humans.

That has led to some not too successful attempts to make them less so. A more recent effort is No CAPTCHA reCAPTCHA, but it didn’t really solve the problem that it set out to.

Some reCAPTCHA are more annoying than others and I think I’ve come across the most annoying of them all.

I found it on the site of a technology outfit whose service makes it easy for developers to deploy Docker Containers to IoT devices. Here are a few screenshots from the site. It took me quite a bit of time to get past the reCAPTCHA barrier.
