It is not safe, few motnhs ago incident has been happened and Rolbit Casino has send user VIP level-based bonuses to verified emails of Stake users. It is matter of glitch to get caught on such attack or agreement since some casinos may sell KYC userbase data to third-parties for making more money. Stake has never accepted their fault and the management has deleted related forum posts on the forum. That is why I don't trust online platforms when it is about my personal info.
