A trusted friend of mine has been sending me spam for the last few weeks. This is obviously hacked or something. But I don't which account is it since his yahoo, facebook, linkedin and what not accounts are all linked together in messenger contacts. He seems blaise about doing something about it, and it is getting tiring to just ignore it day after day! (It is the first message that greets me every day). There is not even an option of "My friend has been hacked" like in Outlook/Hotmail for emails. Where I can report such stuff to Microsoft? Help!
PS: I am prevented from posting a picture of the screenshot!
