I don't see anything that grants you notoriety, and I don't see anything that grants you friends -- acquaintances yes, but not friends. Nor do I see anything that relies on you knowing someone or on them knowing you. I see some statements that you know certain people and how to do certain things. That doesn't need to be established in play because it's part of the character's background. It happened off-screen.
I just have to ask, how can you have acquaintances without knowing them? Because some of the background features such as sailor explicitly state that it's someone you know. In other cases it's because you, or your family, is known.
