I was logging into some of my accounts to check if there was an item that I lost in them, and I came across the following Captcha:
“Using the arrows, find the image where one of the stone towers contains the exact amount shown on the left.” With a crooked number, and an AI-made image with stone towers.
In addition to the visual Captcha, the audio one, although difficult, is passable. But when you pass it, the message “An unknown error has occurred” appears below the login container, and you cannot log in.
The fact that it is impossible is because the arrows prevent the view of some towers, in addition to the stones matching exactly the color of the ground.
Roblox, if your goal is to prevent fraudulent logins from bots, and simple logins from people, you’ve got it.
