I don't think there's ever a good reason to disable the "Back" button
in a web application. If you think it necessary, it's time to rethink
your process.

That said, there are ways to handle it on the back end so that the
user can't submit twice. Have you considered setting a session value
at a point that allows creating the account, and then clearing the
value once the account has been created?

Otherwise someone could just clear their session data and go back to
add more accounts.
