Hi there, I just wanted to point out that for the next step in providing high quality data to OSM, we at Mapillary are preparing to close the feedback loop for the algorithms not only on the mapillary site with blurring etc, but for potentially all other objects like street signs (more to come). You can soon tag things as points and rectangles in MapillaryJS, thus providing feedback on things that are good or bad, and even tag things yourself that you need in your own data, all in the 3D visual environment of MapillaryJS.
There also is a pull request pending for getting MapilaryJS to show up in iD for better visuals than the existing static images to start with so stay tuned!
