The English translation of the linked article is as follows:
“The Vworld operating entity is responsible for this matter. If you are only 'displaying' data by calling the Vworld Open API on OpenStreetMap, there is no issue. (Proper attribution of the source is required.)”

The extraction of data from Vworld is illegal under South Korea's 'Spatial Information Management Act'.

The linked document also states that only 'display' of the data is permitted.

Please take this into consideration.

Unless there is a blanket permission granted for importing data into OSM, there is no feasible way to provide proper attribution. Therefore, this would be considered a copyright violation.
If you feel that a more detailed discussion is necessary, would you be willing to join the Korea OSM Telegram group or the official forum to talk it over?

@CandyRain mentioned the license condition "with attribution." However, unless there is a blanket permission granted for importing data into OSM, there is no feasible way to provide proper attribution. Therefore, this would be considered a copyright violation.

Thanks for the report.
But this is not a zipline.
It's a line that allows you to grab and pull a boat without using oars.

The media confirms that the building was blown up, but we have no information on whether it has since been leveled, so we'll keep it in the 'ruins' state.

Sorry about that. My explanation wasn't clear enough.
What I meant to say is that most of the paths are not definitive and depend on which satellite image is available at which time.
I just checked and it was probably based on satellite imagery from Bing Maps when I edited it.
(When I'm not sure, I refer to satellite imagery from Esri, Google Maps, Yandex Maps, etc. for verification).
So, like I said, I think a lot of the routes around there are fairly arbitrary and will never be definitive, which means that if you or anyone else has more up-to-date information or is more confident, they can make edits.
It also means that it would be nice to have a way of tagging the properties of paths that are not set in stone, that come and go, and that change shape from time to time.
