The best way I think of breaches is "there are millions of people who got their info breached too, so what's the odds that I'll be compromised anyway?"
might be a ignorant thing to do but ya know lightens the mood.
The difference between this and a regular breach is how the info is used.
If it's a list of e-mails/users and passwords, then congrats, you're going to become a spambot.
Something like this though, someone has to pick you out specifically, knowing the risk would be worth it. As Trinick said, it's not something that can be automated, compared to your e-mail shipping out a bunch of phishing links.
