Before knowing about Bitcoin, I used to provide my ID in order to access to the casino both online and on the physical world. Now, since Bitcoin is a part of my life, it will be very insane if I connect my social media account to them. I love to be anonymous and Bitcoin can bring it to me. Gambling without ID will help you to avoid a lot of troubles which may exist during the time you play. Therefore, I never login to gambling site with other kinds of account
We dont know if there would be risk on connecting your personal accounts on gambling sites but yes, it is way much good if you make your profile more private than giving it to a site where they can actually investigate about your identity.
