I don't really care as I used my "junk" email address to register and my story is far from private in my circles.
I do think it's really crappy to mass email this to people seeking support on very private issues. It's very common for people to snoop others emails. I'm assuming this will probably contain advertising content as nothing is sacred when the almighty buck is concerned.
Well, I guess if you don't already know that there is no privacy on the internet, you've been living under a rock.
Hope no one is done any real harm.
