As you can no longer create all-number accounts, you must of already created one in the past to reproduce this issue.
- Go to the Login to ROBLOX page.
- Put in the account information
You’re supposed to be logged in to the ROBLOX account.
Due to ROBLOX auto-moderation, it sees the account you’re trying to log into as “not appropriate for roblox”.
So it doesn’t let you log into the account and shows the error: “Something went wrong. Please login with your username.”
Issue Area: Roblox Website
Page URL: https://www.roblox.com/login
Impact: Very High
If the site prompts you to do a captcha when logging into one of these accounts on completion of the captcha it will say your account login information is wrong all together.
