Whatever their good intention is. It does not belong in OSM. It is certainly no place to publicly document malaria cases. This is IMHO a clear violation of people’s privacy.
On top of that: Their mapping ob anything what looks like a building does uesually not even remotely follow the outlines of the buildings in current imagery.
I agree Stephan. The map is already full of junk edits. I agree with reversion in this case.
Can you also clean up those poorly drawn “shapes” that are simply labeled area=yes. They serve no purpose, often lie over roads, and bear very little relation to actual building outlines.
