So if I find your phone number in the white pages you'll have no problem with everyone knowing it, right? Because that's public information, right?
Some people did indeed abuse that knowledge, but it was rare.
A few people were, by request, "ex-directory" and not listed, but again, that was rare.
Most people were not only absolutely fine with their phone number being public info, it was more useful then than a publicly-known email address is now.
You are likely correct! However, I don't think that anyone here believes the @elonjet account was doing either, besides possibly you.
Also, "and you know it" is insulting and rude, and I don't agree with it or appreciate it.
