JOSM already strips automatically the created_by tags when uploading, but  
only from those objects that the user has modified. It doesn't touch any  
other objects that the user has downloaded and contain a created_by tag,  
so there will be no spam. This way the created_by tags will gradually  
disappear as the data is edited.
