On a recent forum I’ve visited, I really liked the bot check, the question was - Which of the following is an [insert animal here]? And you get to pick from four pictures, and if you have eyes and are not blind, then you will probably guess which one is the kitten.
The problem with that kind of check is image count. If there aren’t enough images, and there usually aren’t, bots can eventually guess the right answer. If the images are of different sizes, that only helps the bot more - once the bot guesses correctly, it can store the image size and look for images of that size in the future, thereby cutting the available image count pretty significantly and raising the bot’s chances.
