I used the word may because a warrant is used to obtain evidence, evidence that is usually used in a court of law, that determines the guilt of a party.

That being said, I take serious issue with TOS being used to shelter one's self from liability. If they are hosting confidential materials (e.g. email) then yes they should be buffered from liability. Once you start publishing materials, those materials are no longer private and there should be much higher standards relating to accountability. But the way things are today, businesses are using automation and TOS to try and hide from the consequences of their actions.
