That is the title of an art exhibit in London created by the husband-and-wife artistic team of Franco and Eva Mattes. (Check out this review by Ted Loos (NY Times) for more details.) In summary, the focus of this exhibit is four video works from Matteses’ series “Dark Content” in which they conduct interviews of anonymous, low-paid workers that companies like Google and YouTube employ to remove objectionable material from their websites. According to Loos’s review, “the content these subcontractors have erased ranges from images of Osama Bin Laden to fringe fetish porn and videos of suicides. One man says a fellow moderator was asked to remove images of SpongeBob laughing.”
