Wouldn't it be nice to have a good study that supports either your or my view?

FWIW, I've never been stopped by Anubis, so even if it's much more rarely implemented, that's still infinitely less than 5-10 captchas a day I do see regularly. I do agree it's still different scales, but I don't trust your gut feel either. Thus a suggestion to look for a study.

Not OP but try browsing the web with a combination of Browser + OS that is slightly off to what most people use and you'll see Captchas pop up at every corner of the Internet.

And if the new style of Captchas is then like this one it's much more disturbing.
