The Netherlands is number one in Europe in hosting child pornography. In order to stem this flow of abuse material, the analysts of Meldpunt Kinderporno assess many millions of photos and videos every year. They send online hosts a removal request and criminal material is sent to the police. We do not see the images on their screens, but in their meticulous descriptions we experience how the images of child abuse pile up and get under our skin: they clean the dirt from our digital streets, but pay a high price for it.
