The picture above gives us a look at the captcha system. Robots cannot tell the difference between two objects when asked for the names of them, as there is no one perfect form of an object that the robots can be trained or learn to distinguish from, only we (humans) can. So, this system's purpose is to rule out bots that create accounts, hopefully leading to the suppression of bots and army advertisers we see around the island of Club Penguin, hopefully leading to a safer environment. I have emailed Disney's support team for CP and they've persisted in telling me that they are getting it under control behind the scenes, and I believe this is one of the more upfront methods they are taking, and I do think it would work well.
Here is what the Create a Penguin page looked like before, for comparison. Notice the change in how colours are chosen, and the starburst that has now been removed, surrounding the model penguin.
Do you agree that the update was worthwhile? I think it is nice to see pages being updated now and again, especially since great improvement has been made with the functionality still remaining. Good job, Club Penguin!
