I agree with your sentiments, but I also understand the parent poster's frustration.
There's a guy living in West Virginia who shares my surname and the first initial of my first name. He keeps giving out my Gmail address to businesses as his own. I suspect he's either old or just stupid, rather than intentionally giving out a fake address, because some of the emails seem to be stuff he likely signed up for intentionally. But I keep getting his appointment reminders, his renewal notices, and other crap - and it's been going on for several years now.
I have, on several occasions, contacted a number of these businesses and explained the situation. They always apologize and remove me... But, six months later, I'm back on their list because the guy has been back in for a service call on his Hyundai, a dental cleaning, or whatever. It's incredibly frustrating.
I have tried contacting him, but it's not as easy as you might think (or else he's just ignoring me). So I can understand the frustration the parent feels, and I can see why someone might succumb to the temptation of moving on to malicious behavior.
