Some users within the community have expressed concern regarding the quality of many MAPS.ME contributions- https://wiki.openstreetmap.org/wiki/MAPS.ME#Questionable_edits
> MAPS.ME provides a low entry barrier for OSM editing, causing an influx of users unaware of rules, guidelines, and conventions (many of which, presumably, never visited this Wiki) and which in many cases aren't even aware that they are contributing to a separate (from Maps.me) crowdsourced mapping project.
