Isn't this a typical Quora answer? Full of filler and shitty hard-to-verify details that provide no value to the answer ("the language is encrypted twice", what the hell), and very little effort on answering the actual question (what is the purpose of CAPTCHA). And the community rules try to block people from writing firm "you're full of shit"-like answers, even though every other answer of Quora is full of lies like…

> the actual question (what is the purpose of CAPTCHA) This assessment isn't quite right. The actual question is about how the captcha differentiates between a human and a bot at the box checking stage.

That answer talks about mouse movements. Most captchas I do these days are mobile. So I don't trust this as a very solid answer.

I know this comment is in jest, but please don't joke on Hacker News as you would on Reddit. Posts like this add little informational content, spawn a thread of joke responses, and take time away from hundreds of people who are here to read high signal commentary. Sorry to be so profoundly un-fun. edit: I'm being downvoted, but consider the comment chain this has generated.

Posts like this add little informational content, spawn a thread of joke responses, and take time away from hundreds of people who are here to read high signal commentary. Here's a challenge: Create a bot capable of generating and posting content like the above that's attributed to "zxcvbn4038." The bot doesn't have to be a…

And it looks like we may already be there:

Yet some more signal for this thread that started with a joke.

Lately I've been getting reCAPTCHA prompts all the time even though I'm not browsing in incognito mode and haven't cleared cookies. All I'm doing is running a very basic ad blocker, using Safari (which blocks third-party tracking), and very rarely loading a Google site. The most interaction I have with Google is when I end up having to use my corporate Google account as SSO for some other site. Given that I'm not doi…

Sometime ago we have a provider that give us everyday different IP. Some days we just were not able to do anything without captcha. It seems that some IP addresses were in some sort of spam base

I recently replaced a bunch of securimage captchas with reCAPTCHA v2. During testing I had to shut it off because it became increasingly more complicated every page reload. First it was just one page of traffic lights, but 20 minutes later I was having to click through 5-6 pages of images. This worries me that user's might get pissed off. I'd really like to know if I've made life harder for my users in an attempt to…

I cancelled and deleted my Spotify account because of that. Now any site that asks me to fill a Google recaptcha is met with a swift click on the Back button.

Well. You showed them, then. I'm sure someone will notice.

Just a suggestion to not say "You're overthinking it" it can be considered pretty dismissive.

Maybe a cultural thing? For me, "you're over thinking it" is a familiar/friendly way of expressing an idea, similar to how you would approach a friend. It was not intended to be dismissive.

you are right. it is a cultural thing. that being said, the advice is sound. the internet is a mishmash of cultures :) if i would bring my culture to the internet, everyone would think i'm troll or horrible person. just because ppl from my culture are a bit direct and cynical :D if you'd like people to respect and take into account your culture it's good to do vice versa.

now that's over thinking :D

You’re overthinking it. I have had a similar experience. The worst were the “stop light” questions. Does it mean the pole, the light, the tiny corner overlapping another square? I used to try to include everything as it was technically true. Very frustrating – until I finally started to not care. Click on the most obvious pictures. Click click click. Done. Get it wrong? Click click click on the next one. Way faster w…

Hell I try to figure out what wrong answers to give to fuck up their training data.

That would only work if everyone who got the same image gave the same wrong answer. Otherwise, the system just keeps sending the same image to more random people until it's satisfied with the consensus. Also, it keeps sending YOU more random images if you obviously don't comply with previously observed consensus.

Everyone should censor and shun white supremacists. They have no place in modern society. When they shed their noxious views, we can all welcome them back with open arms.

Hacker news is awesome today. "Shun white supremacists" getting downvoted, nice.

The obvious explanation is that people were downvoting and flagging your comment because it was unsubstantive and ideological flamewar, not because they are white supremacists.

You continued to post flamewar comments. We ban accounts that do that repeatedly, so could you please stop? We've already had to ask you more than once before.

I’ve had a number of reCAPTCHA incidents where I could not pass the test for tens of images, it was a very frustrating experience. Please do not use reCAPTCHA. The items one is supposed to select often overlap the grids, so it becomes a kind of Keynesian Beauty Contest[1] at that point; I assume they validate based on how much in alignment you are with previous answers, so it becomes a problem of “What nearby grids w…

You probably share your IP with others like Tor or a single IP for a big company.

That answer talks about mouse movements. Most captchas I do these days are mobile. So I don't trust this as a very solid answer.

Mobile device movement variability (IMU, compass, soft vs hard press, and so on) and mouse movement variability are relatively analogous, and both can be measured and analyzed in very similar ways.

It also links to a patent describing a novel mobile captcha invented by the author, so they might have some knowledge about the domain.
