The ones before didn't work or got people banned because it was obvious. I guess not fake but functional Hahaha sorry. Now that we are getting hotkeys (before you had to manually click with a mouse) maybe we can have a serious one.
Simple click-based games like the current coli can easily botted with an auto-clicker script. You can write a simple one with AutoHotKey script. I wonder if the dragon captcha is a randomly generated dragon or will it be selected from a set of pregenerated ones?
