Without these notifications I stay more focused and get less stressed.
If I hadn't deleted my profile, I'm pretty convinced they'd be calling me on the phone or showing up at my house with printed-out notifications by now.
The social networks understand this. I've read that they have algorithms that will batch and spread out your dopamine hits for maximum re-enforcement effect.
My wife wonders why I scan all my groceries at the store and then enter my loyalty card instead of doing it up-front as the system asks for. It's because if I see the price read $130 and then I enter the card and it drops to $110, it feels like I came out ahead. Even though it's going to be the same number.
