My team has recognized that there are a couple of users who are repeatedly making questionable modeling choices.
We've contacted them, and while some specific issues were fixed, new ones kept appearing. We wanted to reach out and to hear your opinions on this matter.
This user is not using existing ways but he adds a new way on top of the existing one, making a lot of duplicates. The example can be:
There is a way that is classified as track, but just over the existing one he added a new unclassified road.
The other type of issue that we recognized is roundabout modeling.
You can see in the provided example that way goes as a part of the roundabout. Also, it is noticeable that half of the roundabout has a [oneway] tag, but the other doesn't.

They have remodeled a couple of junctions so each lane is one way, like here:
What's happening with this remodeling:
* Destination relations are broken;
* Bus routes are not connected properly;
* For navigation purposes additional turn restrictions would be needed to avoid unpleasant turn suggestions;
* In some cases, roads cross each other without an intersection point;
* It is impossible to apply correct lane information.
Another example of remodeling:
There are no physical barriers, so it should be modeled as a single way, but the actual osm data is currently divided based on lane information.
Although we recognize that there are different approaches to modeling junctions, these users are creating a lot of issues by remodeling in this way.
Please can you advise what to do now since I believe that all osm users need to spend a significant amount of time checking all their previous edits?

They are going across Australia and converting multiple way roundabouts into one. We had a discussion on Talk-AU about that, where I have tried to explain why it is not okay to do (since attributes may change within the roundabout), but I can see that practice has continued.
