Huh?! The whole map of Europe is filled with "paint", i.e. [landcover](https://wiki.openstreetmap.org/wiki/Landcover). Just because central Bačka is mostly farmland is not reason to delete the farmland polygons (and you also deleted meadows, scrubland and other stuff). When you delete stuff, how would someone know it isn't forest or wetland? And people use OSM for geospatial analysis of many kinds, not just for car navigation.
