Norwegian broadcaster NRKbeta introduced a feature that requires its users to successfully answer a quiz about the particular article they intend to comment on. “If you spend 15 seconds on it, those are maybe 15 seconds that take the edge off the rant mode when people are commenting,” editor Arnesen told the Nieman Lab. There are more and more tools in the marketplace that recognize “toxic” comments and delete them automatically, i.e. Perspective, Coral Project, Civil or Vuukle that generates additional revenue on top.
