No proof of any sort. Hell, I don't even know if he
is married and/or
has any kids (I don't really care that much about him to know such details). But I wouldn't put is past him, though. Even if he declared something entirely different during some Q&A, that doesn't necessarily mean it's true.
When it comes to the internet, I take
everything with a massive grain of salt. I have enough experience online to know that
whatever someone says or declares, if I don't witness it with my own eyes, hear it with my own ears or able to confirm it myself, the likelihood of it being true falls drastically. With all the BS roaming around online, I've grown massively cynical and very critical.
People are too gullible, here's an anecdote, few years back I was a regular player of SW:ToR. One night when people were arguing about something (I can't quite recall anymore but I think it was something about PINGs as in connection latency), I managed to make some people believe I was playing from the I.S.S. (International Space Station). So yeah, with enough made-up details with just the right amount of repetition, simpletons will believe just about anything. And lord knows there are an abundance of them roaming the web.
