Needless to say, in order to prevent botting, captchas are required for restocking. (neopets' method of clicking the pet in the image was easily beaten). As a user, what kind of captchas do you think would be the most user-friendly type of captcha. Something with similar to what neopets uses when restocking? Math skill testing question? Some other kind?
Anyone have ideas? I'm trying to think of fun/user friendly ways to incorporate a captcha without annoying users too much but at the same time putting an attempt to fight botting.
