I'm not saying that it isn't the address of the actual registree though, I'm merely pointing out a different possibility.
One of my email addresses is very popular to use as a fake address. And a few years back I got tired of it and started to tell people to stop it.
That's when I learned that many subscription services actually make a check that the postal addresses are real, and that people therefore use someone elses address instead.
Nowadays I'm messing with the registrees instead when I'm getting their confirmation email.
People say nothing is impossible, but I do nothing every day.
