I do not want to add my LinkedIn contacts to my phone contacts to my Skype contacts, how do I do to manage my contacts as I desire?

My status is commonly Invisible. Why it is setup as Available when I open my Hotmail account?

This is a very profound privacy issue, that MS is ignoring. Since my LinkedIn contacts are now also my Whatsapps contacts, and so for and so on, I am using less and less of these resources. I am thinking very seriously on cancelling my Hotmail account.
