This is ridiculous. They can simply remove the captcha, and when a user tries to create an account, a message will appear stating that the user needs to verify their email address and when the user completes the verification then the user can continue on the roblox website.
Also, these days when I enter my details to log in to my account or create a new account, it doesn’t ask me to verify a Captcha, it just puts me in to the account.
I think Roblox is trying to do something about this problem.
