To be honest, as one of those who received a follow-up email to the same email address advising a smaller set of breached data, I'm wondering whether it's more a case of that I fall into the bucket of customers who received initial advice of a "small" breach, and then were subsequently informed that even more of their data was breached. However, as a result of email batching / poor timing / mix-up /etc, I received the emails in the opposite order to how they were meant to have been sent/delivered. I'm otherwise not sure why I would be receiving two different emails to the same email address given I don't have QBR, don't share my details with anyone else, have never had another FF account and can't think of any other valid reason for having a "second" profile if it's all based around unique email address.
