yannis323,

OpenStreetMap is not your personal sandbox. It's a collaborative project, with local and global guidelines created by consensus of a community of volunteers. I strongly recommend you read through the Wiki page on edit disputes, which are considered a form of vandalism: https://wiki.openstreetmap.org/wiki/Disputes

On OpenStreetMap, when we disagree with how mappers before us have defined tagging guidelines, we talk about it with each other before going through with major changes. I see that you've been replying on community.openstreetmap.org, and I encourage you to keep doing so. Please stick with one OSM account instead of creating more.
