She is limited to talking and trading with people who are on her friends list for right now so if someone tried she would not talk to them.
If you want to send them via my character I will be sure she knows where they came from.
If you want to verify how overprotective I am, Im sure lizbeth374 would be glad to tell you this is the truth.
But till she gets a little older and has some more game time she is very limited.
