A novel Captcha system that's shaking things up by testing users' ability to do nothing has sparked a lively discussion. The creator notes that this "Proof-of-Work" Captcha remains unaffected by AI advancements, as its compute load depends on usage patterns, not image or audio recognition. Commenters are intrigued by the product's potential, with some admitting they personally struggled with the "do nothing" task due to their overstimulated minds. As one user wonders about the tech behind it, the creator provides insight into how it identifies and blocks bots, generating a buzz around this innovative solution.
