They are non-propagated/effectively hidden.

If you don't "know about them from another source" you can't effectively find/access the information and you might not even know that there is something you really should know about.

The service bridged the gap by providing a feed about what is potentially relevant for you depending on your filters etc.

This mean with the change:

- a lot of research/statistics are impossible to do/create

- journalists are prone to only learning about potentially very relevant cases happening, when it's they are already over and no one was there to cover it
