Maybe he is, maybe he's not on BHW.
Over the years, Matt has mislead webmasters about what is "acceptable" seo practices and what is not. Then, to turn around and target those same practices he said was "acceptable".
Matt and Google are known for intimating webmasters and seo industry. I think that this is another intimidating ploy by his part. Trying to scare BHW users, that he is watching.
I don't care if he is or not.
Matt and Google are nothing more than bullies and trying to strike fear into everyone.
My 2 cents.
