Facebook sends your information to CIA

That clause is in like every site for uploaded content, isn't it?

Yep.
Just like how Nexon reserves to the right to end services whenever they want blah blah blah.

Here's the actual citation,

We reserve the right to remove or modify any content you provide to us or otherwise post on the Site at our sole discretion and without prior notice or any liability to you. You represent, warrant and agree that none of the content you provide to or create using the Service violates any third party’s intellectual property or other rights or is subject to any obligation, whether of confidentiality, attribution or otherwise, on our part and we will not be liable for any use or disclosure thereof.
