For backwards‐compatibility purposes, we must support usernames which begin with a digit. However, there are a number of reasons why these are not ideal (e.g. 3 apples @25¢ each). We should forbid future registrations from beginning with a digit character (containing a digit elsewhere in the username is fine).
