People do not care much about their business email being hacked

Couple of days ago a scam team, in order to sign up for premium membership on postjobfree.com -- hacked couple of real business emails: jdicken@c21patt.com and heidi@heidiburns.com
Both emails seems to belong to real estate agents.

I was able to find and reach actual owners of these email addresses on the phone.
They do not seem to be very concerned about their email addresses being compromised.
Both email owners confirmed that they did not make premium orders on our web site and then indicated that they prefer to continue with their other business instead of digging deeper into that email hacking ...

How much would you care if you learned that your email account was hacked?
