Quoted from ForceFlow:If you think that if your home address getting out in the open doesn't matter much, keep in mind that hackers are also sometimes pranksters. They could send glitter bombs, dog poop, order a pizza for delivery, or even go as far as to swat the address. If you don't know what swatting is, that means someone calls in a fake emergency to the police. People have died as a result of this with police arriving at the address thinking it's a life-or-death situation based on the information given in the fake 911 call.
So yeah--an insecure website containing personal information can be quite a serious matter these days.
[edit]: If you would like to check if your email address has been listed within a known data breach, this is a legitimate website to check with: https://haveibeenpwned.com/
I realize the risks, given my many years in Law Enforcement, but I would add that about anyone with any kind of keyboard competency can obtain address info pretty easily, along with a ton of other stuff that you would never think of. There are all kinds of public databases out there....you just need to look in the right place. Ever hand someone a written check? I know they are less and less common these days.....but you realize you just handed them your bank account and routing number, along with your name and often times your address and phone number. Doesn't make it right...and I am not saying you should not protect the info....what I am saying is not to have a false sense of security because you only frequent so-called "secure" sites. And the guy that "died" because someone swatted his address.....that address wasn't even correct. It was a fake address one person gave to the other as his own when they were arguing....the problem was, he pulled it out of thin air. That could happen to anyone at any time. In the KS case, the guy that got shot was completely innocent, and having his address published somewhere had absolutely nothing to do with the case...he just had the mis-fortune of living at the address the guy made up.
