My old main account was deleted for something I didn’t do, and couldn’t manage to get it back (March 2022). That account was logged into DevForum under the same Email the account I’m on has. This is a problem because Roblox Support is unable to unlink my deleted account from the Email adress, which in turn makes me encounter the “cannot use different account with the same Email” error upon logging in. The only workaround is to change my email to a different adress, log in, then change it back to the supposed one.
I understand this may be in place to prevent account spamming, but it was proven many times to not work and it would help my kind’s cause of easier logging. As for the reason why I need to re-log, the DevForum does not sync information from Roblox such as Display Name or avatar headshots.
