Reasonable. Just look at its name.

Interesting use of "its" but it is entirely possible that a robot has a preferred set of gender pronouns, and you just mislabeled them. Many of our assumptions support the biopatriarchy.

Robots find the use of "biodiversity" is discriminating.

I think that's very unlikely. There are over 100,000 new accounts created on Twitter every day so we would expect a large and frequent amount of bans if what you are saying were true. Furthermore most Twitter visitors don't have accounts so it would be pretty foolish to base their anomaly detection on a metric that most of their visitors fail.

It's actually well known that you'll get blocked by Twitter within the first 2 minutes of registering, whatever you'll do. They probably use it as a way to enforce their "soft" requirement of a phone number. After verifying that you have a working phone number, you'll get unblocked. Also, Twitter routinely renders their tweets unaccessible to non-logged-in users, due to rate limits on their api (which is used by thei…

So basically if the phone companies lowered the price of buying number lists then a bunch of web2.0 companies' valuations would evaporate?

At work we have a scraper that likes to use a particularly expensive search query using hundreds of different ips dozens of times per second, all so that they can scrape data that is freely available from us as an XML feed at a different url. Every time I found a way to fingerprint and block them, they'd change their bot to avoid detection. Captcha for rate limiting seemed like the least bad option. However, eventual…

Rate limiting can be achieved without actually inconveniencing regular users. Put a exponentially growing delay on the server's response for requests coming in too quick succession.

The problem was that with the sheer number of ip addresses they were using, and with the rate that some normal users used that particular endpoint, regular users would have been inconvenienced--either by being forced to wait or by being forced to do a captcha.

I would have set it to only show the captcha if the delay was active, so users would effectively have had a choice of wait or captcha.

I had Microsoft do this. They notified me that my account was being suspicious, so I needed to provide a phone number to use it. I had literally just made the account though, zero activity at all. It was just to force me to give a phone number to them for their data harvest

Just throwing this out there. Have you considered that maybe you are a robot?

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.

I checked the HN guidelines, and I didn't see anything about humor. I did find this, though:

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…

Same here. I have an alternative browser with no ad blocker, no tracking blocker, and sometimes I just copy the website from Safari to that other browser to avoid CAPTCHA.

I feel like a "bot" with access to control your mouse and read the output from the graphics system (aka get an image of the screen in real-time) could have little trouble with these things.

Yes, but as a spammer, you would need access to lots of different people's mice and screens. A bot net would do it I guess.

That's what ReCaptcha always was... it was originally a known and another unsure text blurb from scanned books/text documents. Now it's street signs etc.

It's actually pretty interesting to see how the captchas have evolved as, presumably, Google decides "OK, we have enough data to consistently identify this thing" and moves on to the next challenge. I recall the modern (non-text) captchas used to be cars pretty much every time. Then, the images started getting grainier as they apparently wanted to improve their recognition in different conditions. Then crosswalks and…

And I find it equally interesting to think about what happened to Google Books project after half the world was entering text into captchas perhaps close to a decade? Is the project still going on?
