Comment 5 for bug 551906

I agree that we could do the rate-limiting in a more forgiving manner that would still prevent the spam problem.

However #1: I can't really think of a use case where it makes sense to let a user try again when he/she is trying to create an (/another) account with an email that's already in the system. The already-existing account should either be deleted (and so de-conflicted) or recovered.

However #2: It would likely be easier to change the rate-limiting scheme than to implement any of the account-deletion/recovery changes suggested in bug #552603. So I'll mark this as not-invalid.
