And no, I can't answer for everything he does/ has done, but it is possible to be frum and do things that are wrong. I don't think he ever intended to be a frum poster boy as much as a Jewish concept/value poster boy, which I think was his kavana. It's everyone else who decided for him that to spread Jewish values he's got to be as religious (or more so) than us, rightly or wrongly. He's not Chabad's 'success story' and he's definitely not anyone's Rav. Just a BT who ended up in a serious spotlight.
