The fact is that the mappers are shown to lie, they know they should not get it from Google, or from duckduckgo so they lie by omitting the fact that they did from the comments.
The fact is that there is very strong indication that those mappers are NOT mapping according to the principles of OSM: checking on the ground. In fact, that is the main conclusion any mapper will quickly come to if they look at the entire XBT dataset.
Do you dispute those facts?
These are not new worries; you were told about these worries already in an earlier thread, but it only got worse since then. You are still not acknowledging that people HAVE TO CHECK ON THE GROUND before they map.
