The only reason is that GE is making an April-joke with us. I've checked the myplaces, exchanged it by the default one and it's still there. So the changes made to send us friendly visitors must coded somewhere else. And the only institution can do that is GE.
Edit: I am pretty sure it's GE, not GE-Skype. I've started my notebook haven't used the last days and the visitors are there too.
