Maybe it's because I'm in a regulatory position, but that kind of stuff is really vile... if that's what happened, of course.
I have no idea. The address used on the original mailing list would have led where the letter arrived, and a google of my full name would have done the same thing, because my father and I share a name, though not in the same order. If you recall, I stayed with him for a while when my kids first moved out here with me. That was when the first mailing list went out.
And it was a BIG list, if you recall. Well over a hundred names, and at least 5 of those people have since joined My People, and have expended a great deal of effort in the past with the intent of making my life difficult. 3 of those people were not on the second list, which used my current address.
On the other hand, I haven't been particularly careful with my last name, and a google of that would lead to my father's doorstep, as I have an unpublished number.
