Hello!

I'm the author of mCaptcha. I'd be happy to answer any questions you might have :)

For context, mCaptcha was discussed in these threads in the past hour before being posted on here: [0]: https://news.ycombinator.com/item?id=32339922 [1]: https://news.ycombinator.com/item?id=32340424 [2]: https://news.ycombinator.com/item?id=32340305

https://mcaptcha.org/docs/prologue/introduction is a 404. (It's the link behind the "Get Started" button.)

A one-sentence describing exactly what it does and how it works would help ;-)

yikes! The docs had an overhaul last week, that link was removed as part of the overhaul. Should have paid more attention. Should be fixed now :)

Here goes nothing:

mCaptcha is a privacy-focused, highly accessible CAPTCHA that uses Proof of Work for rate-limiting. It makes the bot/spam spend more time and work sending the request than it takes for the server to respond.
