Those are the main reasons I never post anything in my personal facebook, in fact it's been ages since I don't post anything there, I just use it to check what my friends are doing.
Those are also the reasons why many of us here like to play with bitcoins, if you find a good casino/sportsbook which has a really good layout and also works like a charm in mobile phone too, then this is my and I believe many other people's choice here. No one can check your phone if you play in incognito mode, not even your girlfriend or wife.
I play asian sportsbookie, they accept bitcoin for deposit and withdrawal. Is it something you looking for ?
