Hello,

I have a friend that asked me to make the question here...
Anyway.. she said me that today appeared on her WLM 3 unknow people talking to her without any "adding invitation".... She told me that the message on the Person's Window was the warning on the "Yellow Bar" that the person wasn't on her contact list (see image attached), and realy, it wasn't (she told me).
Also, on Opitions, on the Privacy, she has bloqued the "All other contacts"...


Now the question: How to stop this from happening???
I've told her to imediately block the people (as you can see on the picture, the Block button can be used)... Any other ideas???

Edit: i thought on Server Bug, but.....
