Windows 10: Contacts in Skype

Hi, I just installed Skype on W10, and it's automatically given me a whole bunch of contacts that I've never heard of. I can't delete them from Skype, so where are they? I don't have any contacts in Outlook, and they aren't in my Gmail either.
Where are they, and how do I get rid of them?
I un-installed the default W10 Skype, and installed the downloaded generic version, but they are still there.
Any help please, or is this another instance of Microsoft saying "There, there, don't worry. We know what's good for you and your computer."

Lumia 920 - Problems that should not be

Sorry but maybe my description was not clear. The problem is that the new skype contacts are the old messenseger contacts. So Skype contacts appear in the contact list as skype contacts and you can make a cal, but new skype contacts are only recognized
as Messenger contacts and you can only make a skype cal to them if you open the skype app

 

Skype Preview Windows 8 Issues and Bugs

Ill start us off. I have merged my Skype and MS account together as is the option when you install Skype preview. Now I have a strange bug\feature on some contacts but not all. When I select to Skype a contact from my people hub it loads Skype but in
messaging mode, I have to back up and reselect the contact in Skype app to start a phone conversation. It seems to be contacts that have both MSN and Skype accounts , and Skype auto selects the MSN contact and not the Skype one.

 

In the desktop version of Skype when you click on the unknown contact once you should get the option to add to contacts or block.
Select Block and then select mark as spam.
They will then be placed here:



and you won't get any notifications from them any more.
You might get new ones once in awhile, but it will peter off after some time, when you keep reporting as spam.
I have the suspicion it's Bots phishing, working like an auto-dialer with telephones, trying to find a good/legit "number", then the spamming really starts.
