For scrapyard, my partner and I worked together to make a demonstration of what we thought simulates the captcha verification web standard along aided with unclosable, unskippable, unblockable and depending on the intensity set, very obstructive advertisements for the year 2035. Just like current day captchas, not everyone can make it through. Regardless, the most important point is make sure you're a real, breathing human.
You can customize of the simulation intensity with the slider on the page.
