Yes.Didnt YoshiP address this point directly and say that the current set up is intentional?
It borrows both from an eastern idea of human interaction, and from older MMO's where friends list were one-sided for both players.
Its an incredibly small game world with multiple ways to find you, this one specifically requiring you to have said "yes, this person can forever have me on their friends list if they so choose".It should be borrowing from the GLOBAL idea that stalking is bad.
You cant fix stupid or malicious, you can only deal with it when it happens.
The vast majority of "stalking" in a virtual world is fixable by blocking/ignoring the person than then following through with that.
