Those Google captchas are horrible. Often they do not let one of through despite giving seemingly correct answers. One is prompted with captcha after captcha after captcha. They not only require cookies, but JavaScript turned on and are a real affront to the whole idea of a usable, open web. On tor, I just give up. There is nothing I want to see on the internet badly enough that I'm willing to spend ten to fifteen minutes (this is not an exaggeration) trying to guess what I'm supposed to click on. I do blame cloud flare, ignorant website creators, but most of all Google. Out of the many atrocious products they have created, nothing is more infuriating and frustrating than these stupid captchas. They are not logical and quite often simply unsolvable. I support the creation of bots that can guess (because that's what the process is, there's no solving these) these even if it comes with all the downsides of having such bots roam freely on the internet. I hope the ai of the future is able to deal with such nonsense to the point where Google gives up on this atrocious technology. I'd rather have spam and ddos attacks than this.
At some point, Google started doing really aggressive increases in their captcha difficulty based on IP trust or even outright refusing to let people try and solve them at all. Since there's going to be a large overlap between IPs that Cloudflare force through the captcha and IPs that Google distrust, this means that anyone trying to access the internet through a network that Cloudflare has put on their evil list will probably find the whole web completely unusable. Of course, any employees testing the captcha feature will go though the easy path and not see the problem...
Captcha's are very overused. I cancelled my PlayStation Vue service because the website
kept bugging me with the worst of the worst Google captchas every couple days or so (not using Tor). Unreal that anyone thinks those are a good idea just to log into a service someone is paying for.
I think the number of times a captcha is presented is directly correlated with the risk associated with the IP address. But you're right, very annoying indeed.
