What if we could restrict certain group to see our connections?

You know, Steam scammers, sadly, still a thing. They pick a random person, look at that person's profile, they're looking for Steam connection. Ding, they found a victim! 

"+ Is this your Steam account?

- Yeah, it is.

+ I'm sorry, but I misclicked and reported you accidentally. I want you to talk with "real" Valve employee. Otherwise you'll get banned."

And then that "real" Valve employee forced them to take their login credentials, by threatening them to ban their account.

If it sounded like very specific, no I didn't experience this. No need to worry. But really, blocking certain people (let's say, only our friends can see our connections) to see our connections would prevent events like this. Or, even better, we can block specific connection too!

Things I request:

- Preference choices to make connections visible to certain groups (such as Nobody, Only Friends, Everyone options etc.)

- Choosing to hide or show individual connections to groups, for example I can choose to show my Reddit account to everyone but my Steam account to only my friends
