I mentioned it in my OP, but the post that is being replied to (from TotalBiscuit) was on the front page of Reddit. (TB is not an internet identity I have any interest in either, generally.)
That means it is one of those things you can easily stumble across without being a member of his sub-reddit - the title (about the pitfalls of being internet famous) was intruiging. Which is how I got there, and I would assume, so did the author of the reply.
Not actually an unlikely event for a high priest of Procastidemus, such as Scott.
Further, I would expect Bakker to use an obvious thowaway account name after his westeros 'sock-puppet' debacle.
But yeh, just further explaining why I thought it was a possibility.
