Where I work, we have developed a nuanced philosophy to describe the niceties of collecting data, managing it, validating it, and preparing it for use: “Data is hard.”
This was brought to light in a very public manner by the vandalism that was displayed on basemaps produced by Mapbox. The responses by Mapbox and their CEO, Eric Gendersen, are good examples of how a company should respond to such incidents. Kudos to him and the team at Mapbox for addressing and rectifying the situation quickly.
Speculation quickly ran to vandalism of OSM, which is one of the primary data sources used by Mapbox in their products. That speculation was backed up by the edit history in the New York area, but it is interesting to note that the vandalism was caught early in OSM and never came to light is OSM itself. In this case, the crowd worked as it was supposed to.
