I registered at one casino and was bombarded with endless spam to my email, plus phone calls. I don't want this anymore. I need a place where privacy is truly respected. What can you recommend?

I switched completely to parimatch-online.in for this very reason. They don't spam you, and there were no calls. Yes, you receive notifications about bonuses and promotions, but without being pushy - 1-2 letters a week at most. And a phone number is not required for registration at all. Everything is quite delicate and without pressure. Plus, you can immediately turn off mailings in the settings - and silence. I think this is an indicator of respect for the player.
