Who are they? How does it all work? What would happen if captchas weren’t there?

They aren’t robots, but code that just spams websites with login combinations until it finds one that works. This is called a brute force attack. By adding a step where you have to identify pictures, it makes coding a way around it so difficult that is practically impossible.
