They still call them refs...
A lot of teams have been playing cheaply this World Cup.
I remember watching the US - [I forget] game, and all the players on the opposing team kept making blatant attacks on the US players; like elbows to the nose, stepping on ankles, fists to the face - and the refs weren't calling anything.
But the Brazilians are generally just a really cheap team. Without attempting to over-generalize, it's pretty true that the South American teams and Spain tend to dive a lot, and take a lot of cheap shots at the other teams. That's no fun to watch.
