Less effective in what way? The actual answer is their use for training AI isn’t as good, but that’s not what I think you (or most other people) mean. The main use of them is to train AI via humans, the security is secondary and just a smart way to get free work.
But it should be lower case “p” at the end
Capchas aren’t generally case sensitive though.
They’re not? Doesn’t that make them less effective?
Probably? I’m no expert but I always answer with just lower case without issue

Less effective as the intended use of a CAPTCHA. Not as AI training.

u fr? Captchas were used for bot protection, originally.
Depends. I know that Microsoft changed to non-case sensitive not terribly long ago (for things like testexchangeconnectivity).
