I've now had it twice that people used my chess.com games to prepare for me. Since there's an endless amount of those, you can obviously get very deep opening information on your opponent in every conceivable variation. Worse yet, when you googled my name + chess, this is one of the first sites that showed up. It actually made me change my name on here, so as to not appear on google anymore. I've since changed my privacy settings to "May View My Blog": "Only my friends". Does this mean, other people can't see, less download my past games on here? Or what is Blog referring to? 
Is there any settings change to accomplish what I'm looking for?

All games played on Chess.com are public.  Anyone can view any profile and view their entire game history played on the site. There is no setting which prohibits this function.
