> with your entire online identity

Seems like one account for idendity (gmail and personal gemini assistant) and another for everything else would be a best practice.

Google can and will block any linked accounts as well. For some reason I'm not allowed on AdWords. I have tried making new accounts and they always block my ads. I don't know how they figure it out that it's me. Other people on the same wifi have no issues running same ads (for same YouTube videos).
