Hm?

Before NexusPIPE ramped up their security, one of their captchas that they offered as a part of their services was a simple puzzle piece slider. Using pixfinder, I made a very quick userscript for Tampermonkey that would recognize the puzzle piece shape in the captcha image and move the slider to the appropriate position.

The reason it worked so well was because the noisy puzzle piece cutout was actually using colors that were not in the rest of the image (like pink, cyan, etc). I was not the first person to discover this, and in fact, the user Mxtthew on v3rmillion legacy utilized it better. This script stopped working after NexusPIPE updated their captcha to make the entire image noisy.
