forse si potrebbe creare un task nel task manager per "curare" la malattia prima di procedere con l'asportazione? ---------- Messaggio inoltrato ---------- Da: "Frederik Ramm" <[email protected]> Data: 27 ago 2017 3:50 PM Oggetto: [OSM-talk] Redacting 75,000 street names contributed by user chdr A: "Talk Openstreetmap" <[email protected]>, "[email protected] Openstreetmap" <[email protected]> Cc:
Hi, > > in 2010 I was privately contacted by another OSM user with the > suspicion that user "chdr" might be copying names from Google maps > (there were few "easter eggs" in Oman that were only on Google and not > in the real world, and they suddenly popped up on OSM). "chdr" was > contacted at the time, but continued unfazed. In 2013 another mapper > lodged a complaint with DWG about edits by chdr, and I emailed chdr > asking him about his sources. At that point chdr stopped mapping. He > never replied about his sources though, even when I set an ultimatum (of > 31st August 2013) threatening to remove all names he contributed if he > can't tell us his source. We do have to assume that all names > contributed by chdr are copyright violations. > > (chdr has added names all around the world, making a harmless survey > unlikely.) > > For various reasons I neglected to act on this, and was only reminded > now, 5 years later, when DWG received a complaint from a user in Brazil > where chdr has even used "source=google" occasionally. (But as I said, > the suspicion is that Google was used throughout.) > > I have now compiled a list of all street names that were contributed by > chdr and are still visible today; we're talking about almost 75,000 > street names world wide.
