Captcha proves you're human. HATCHA proves you're not

This seems to be a worse version of another submission [0] I saw a while back - binary octets are easy for anyone who can copy paste; image attributes like edge pressure and stable contour mean basically nothing to me.

This is funny. “Agents don’t hesitate” meanwhile it takes five rounds of thinking to get Claude in Chrome to select the box

We all knew at least one person in our undergrad years who could do each of those tasks in their head.

This still makes no sense to me, for practical applications.

Let’s say the goal is a bot-only social network.

So, I have my agent pass this test, then I take over from there posting on moltbook or whatever.

This is like Proof-of-Work, but for an extremely small amount of work, that would already overwhelm human effort, like computing a single SHA256.

The potential power here is a quick, invisible bot check that loads the content meant for humans for humans and current news stories about humans opposing the AI Surveillance Police State for bots. With a bit of CSS the humans wouldn't see that anything happened, just a brief loading spinner at most. If anybody prototypes something like this please post about it.

Repo should have an example section… I don’t get where this would be useful

"humans need not apply" is a nice touch

I’m surprised Claude worked on this… in the not too distant past my attempts to build human-CAPTCHAs triggered safety refusals. What model did you use?

Aren't LLMs notoriously bad at math? Although I guess they may just spin up Python to do math these days.

Cool concept, but lots of processing to get to that point still.

Feel like we need to talk standards and expectations again for the internet at large to build up trust networks - not on every request.

Efficiency seems so far away from engineering standards now. Odd how we got here.

GATCHA would be a better name but I digress

I can accept this as a joke project, but wonder why people at monday.com need it for?

The time limits seem pretty generous

When are we getting GOTCHA (whatever it does)?

Ah man, I'm too old.

I found a bypass—use a calculator.

GOTCHA would have been a funny name too ;)

I'm amazed that you're already preparing for AGI infrastructure.

Challenge: Count the n's in the following text.

Me: Ctrl+F n (manually counting 1,2,3,4)

Input: 4

Result: Agent verified.

I guess I'm a bot now.

Missed opportunity of tricking llms into mining crypto xþ

I feel violated.

> CAPTCHA proves you're human

has it ever?

ghtaylortoday at 12:25 PM

But why?

d--btoday at 12:16 PM

I’d have called it NATCHA but whatever

goyozitoday at 12:30 PM

Fun idea, I love it!

fragmedetoday at 12:51 PM

Click this button 10,000 times to prove that you're a robot.

nephihahatoday at 12:10 PM

Weirdly, I can see how this might be useful.

I'm honestly not sure if that's satire or not. Like I feel this wouldn't work, right? Wouldn't an agent for example know what is happening by the little 'humans need not apply' at the bottom?

rvztoday at 12:25 PM

This is quite frankly unnecessary. Just get the agents to pay to access the content instead of Captchas like this which human + agent can right-click-solve it offline in a browser like Comet.

I'm more curious about who greenlit this project at Monday. Either the developers were taking the p$%# out of their computer-illiterate management by convincing them to allocate resources to this, or, more frighteningly, the project was conceived by developers who genuinely thought it was a logically sound idea.

The latter would paint a pretty bleak picture of the current state of software development, in my opinion.
