But for actual live users who don't see anything but a transient screen, Anubis is a better experience than all those pesky CAPTCHAs (I am bored of trying to recognize bikes, pedestrian crossings, buses, hydrants).
The question is if this is the sweet spot, and I can't find anyone doing the comparative study (how many annoyed human visitors, how many humans stopped and, obviously, how many bots stopped).

Most CAPTCHAs are invisible these days, and Anubis is worse than them. Also, CAPTCHAs are not normally deployed just for visiting a site, they are mostly used when you want to submit something.
