Hehh..  As you well know, there are many folks that invest=20

It enables visibility and transparency which can be employed to=20
inform measurement and detection systems.  IF / how an operator=20
chooses to apply controls based on that information (e.g., drop=20
a prefix originated from an unauthorized origin AS or leaked via=20
a known bad path) that's certainly their prerogative.
