They're a private company, they can ban whoever they want.

Or at least that's what I heard a few years ago when it was politically incorrect people complaining about being banned with no accountability. They're a private company, it's their servers. You may not even be paying anything. So they can do anything they want to you and you have no cause for complaint.

They absolutely have the right to ban people from their services. But they shold explain what terms of service were violated by what user actions.
