I think this is a big mistake. Low quality of Bitcoin-related OSM nodes should be removed by users directly within coinmap and that should also reflect OSM data.
It is, but not from my side. Coinmap users neglected to do proper checking and cleanup of the venues and OSM people were quite unhappy about it and stated it was my responsibility to keep the data clean. This was not possible, because of the lack of time and almost no donations to hire people to do that.
For example: what if someone wants to create android version for bitcoin places and most new nodes are added within coinmap? How is this going to auto-sync?
There is an api for that
https://coinmap.org/api/, so apps can use that.
