Wait, now you have me wondering: If this is just javascript from another domain, what's preventing bots from proxying requests, intercepting this one, and replacing it with a dummy function that returns a "no threat" score?

So... the answer is, nothing prevents it?

When the API reports a failed verification, the webmaster knows that the response has been tampered with?

I don't care if every site that I browse using this VM knows that I'm Mirimir. I don't even try to hide that. What matter is that my personas using other VMs, through other VPNs or Tor, don't get linked to my meatspace identity, to Mirimir, or to my other personas. And that's doable, I think.

Yes, and you go through quite a lot of effort to achieve that, given your other comment. My main point is that the amount of effort you have to go through to achieve that is very high, and I wish it was considerable lower. There are technological changes that could help with this, and legal changes that could help with this. I think a comfortable place would be if you visit the same online location using your main br…

> Yes, and you go through quite a lot of effort to achieve that, given your other comment.

That's true. However, it's mostly one-time effort. There are Linux and TrueOS workspace VMs, pfSense VMs as VPN gateways, and Whonix gateway and workspace VMs. All in VirtualBox.

There's ~no configuration required for the Whonix VMs. You just need to point the gateway VM to the pfSense VM that ends the desired nested VPN chain. And if there are multiple Whonix instances, rename the internal network that the gateway and workspace VMs share.

For the Linux and TrueOS workspace VMs, it's just like any OS install. You do have more machines to maintain, but mainly that's just keeping packages up to date. All of the devices are virtual, so you don't have driver issues.

Setting up the pfSense VMs is the hardest part. But once that's done, you can use them for years. pfSense is pretty good about preserving setup for OS upgrades. And there's a webGUI for changing VPN servers. But it's harder than using a custom VPN client.

So yeah, it's not so easy. However, someone could write an app that papered over most of the ugly parts. That even automated VM setup and management.

Your comment adds a lot to the conversation, so I don’t want to be more contrary than necessary. It’s nonetheless a shame that it’s so universally misunderstood how ad-supported megacorps make their money that even highly sophisticated users of the web still talk about the value of personal data (source: I ran Facebook’s ads backend for years). Much like the highest information-gain feature for the future price of a…

That may be the case for some people, but that is not my complaint, nor that of many folks I know. I simply don't care how FB, Google and other surveillance outfits mak…

Exactly! And this is my problem with Apple too - sure , they do some things right and are more conscious of "user privacy" than others, but at the same time they have also started abusing this to further spy on their users.

What use is "we are transparent with our users about the data we collect" when the user does not want you to collect the data in the first place? And they give you no option to opt out of such data collection? (And for what - just so that they can create a better ad network that can better exploit us with our own data?)

(And don't get me started on Safari spying and all their "anonymous" cookie collection crap without giving the user any choice in the matter, essentially forcing everyone of their users to opt-in to be profiled through their browsing history).

Does not work with Tor. The plugin requires "privacy passes". Those passes can be obtained by solving captchas, but when trying to do so, one is greeted with this message about being blocked: https://i.imgur.com/qXJfl6J.png

Slightly off-topic, but the users who use Tor regularly, how do you do that? For me, it has been terribly slow every time I tried to use it.

On Tor I get roughly 700 KB/s speeds, which isn't terrible for me

This is the answer. It seems that most website owners are somehow super scared of a targeted attack, since it is indeed trivial to bypass (and they realize that), even if nobody will take the time. I've heard stories from people that own small sites and still have someone targeting the site with custom scripts, but never anyone I know (not even a friend of a friend, only ever random people on the internet). But there…

I've had received attacks from custom scripts to post spam in a blog that nobody read. I changed my custom robots tests a couple of times, and each time it took a few days for the bots to adapt. At the end I removed the comments section, so there was nothing to attack.

This is exactly the kind of story I'm taking about. I'm sorry about your experience, I don't doubt that you're real, but this is the kind of confirmation/hindsight bias that makes people misjudge risks. I expect you are an outlier, but I have no idea.

Might be interesting to poll random people that have websites with <100 unique visitors a month for this sort of thing to get us any sort of idea of how necessary an invasive CAPTCHA like Google's is.

That would be a useless site, but that's not how I read it. I understand it as "this is not that Google thinks your account is a bot, it's that this request might be made by a bot. And since you didn't use this site as a normal website, it also doesn't score your type of traffic, just this one request". You might be right, but it really does seem to be doing a request to their API.

>That would be a useless site looks like it is a demo of the API for people wanting to consume it. knowing what the payload looks like is not useless at all in this case.

Documenting requests' format and their return values is documentation and doesn't require an interactive site that looks totally real and makes you expect a real (rather than a dummy) answer. Which is not to say it's impossible, but it would be weird/unlikely. Usually when there is an example api request in documentation, it's a real (live) request, too, and this isn't even a documentation page.

This looks like a RNG: I got 0.7, 0.9, and 0.1 successively. It can't make up its mind whether I'm almost certainly not a bot (0.9) or almost certainly a bot (0.1)?

> This looks like a RNG Come on, how is everyone in this chain so blind. It's literally in bold and the single largest block of content on the page: NOTE:This is a sample implementation, the score returned here is not a reflection on your Google account or type of traffic.

Please see the sibling comments (that were there before yours) where this is already being discussed, before being insulting.

And what is that compared to any regular browser?
