I think it's an extraordinarily bad idea to change people's passwords without prior consent. It happened and I was lucky to be able to log in. I used a throw away e-mail address when I signed up for this site and it was nothing of a miracle that I was able access your e-mail about password changes.
I used to be with it, but then they changed what "it" was. Now, what
I'm with isn't it, and what's "it" seems weird and scary to me.
