Forewarned is forearmed. While you can’t get back stolen data, it’s in your best interest to know you’ve been compromised. For example: I’m getting spam from lately and the return email addresses differ from what is shown. So, it makes me wonder, “How did these people get my email address?”
Twenty seconds with Firefox Monitor told me I was in two major data breaches. Yeah, you’re right. That could have something to do with it.
