Not from CP imo. They can see the equips on your char, what are in your items window, stuff in your storage, how you obtained them when you are online or offline. Pretty much no privacy there, lol.
But hey, same things happen in real life too.
P/S. I think Magellan shares his acc, so he wants to know what others have done with his acc. That's why he asked for that function, lol.
@Cassie: would be super nice if we can manage our storage in CP, wouldn't it?
