I think that they should do that to the people for helping them if predators that trying to get all your information.

If they keep a eye on it they can prevent deaths, and other serious things. 

If the people start putting like a password on the information, or a virus to protect themselves from predators.

To never give information with who your chatting with.

If they read there comments they can prevent many things.

If the security in that is monitering we can save lives.
