Ok but it’s still a jerk move that none of us would want to experience, right? Like can we at least agree it was malicious and unwanted?
Unwanted? There's been a big cultural shift over the past 100 years about addresses. Papers used to print subjects' addresses alongside the subject. In the 80s addresses were still considered public knowledge via phone books. So maybe Douglas Adams didn't want his to be public, but he would have been in the minority. Either way, there's no evidence (here, anyway) that he gave it a second thought.
It was an entirely different time indeed!
