Well wrong, because the contact has at the momment no pc and there is no pc she be on, when the spam is comeing in adium:

How to prevent this? Greetz

Tell her to go to http://account.live.com and change her password, because it seems that her login credentials have been compromised somehow, and her account is being used somewhere else, probably on a remote server somewhere. Changing the passowrd (to something secure) should stop that from happening.
 
I knew of this 'Privacy' setting from searching before.

But I had to start over with a fresh install.

This 'Privacy' setting doesn't show up until you create a account, select it and then choose 'only allow contacts'

Makes sense it doesn't show up until you choose the account you want to apply it to, but I still spent some time trying to find it.
Once I added my IM account, then it shows up.
