Wilfred,
 
Wv> It was self censorship. After the police in Brussel asked people not to
Wv> post pictures of the events in the Brussels streets on social media, as
Wv> to not make possible terrorists any wiser, people started posting (funny)
Wv> pictures of cats.
 
That's part of the story.
 
Authorities asked not to report on police-activity via social-media, especially
a number of specific hashtags.
 
A few wise-guys from North African descent, and I'm not profiling anything or
anyone here, did so anyway. Where-upon some people started inundating those
hashtags with cat photos to virtually bury anything with an indication to
police activity.
 
After appr. 24hrs 190.000 cat pictures had been published and republished and
... retrieving any useful information for terrorists had become virtually
impossible.
