Hi WT Hundu. While mapping some waterways, I noticed very small residential areas in a larger residential area here https://www.openstreetmap.org/way/1389490341/history#map=19/7.342733/9.705768 This is not usually correct.
Then I noticed that they appear to have the names of people living there. This does not follow the rules of OpenStreetMap, described here. https://wiki.openstreetmap.org/wiki/Mapping_private_information.  The small residential area should probably be removed. However they could be replaced with individual rectangular or round buildings with building=yes, but no personal information. If you personally know they are houses, then use building=house. If you have any questions, just reply to this comment.
Regards,
Adrian
