OpenStreetMap 開放街圖
The problem
A new user accidently added addr:city and addr:province tags to a large selection of objects, including rivers and individual nodes.
The user mentioned that the tags were intended only for buildings, so thought I would document the cleanup for future efforts like this.
Finding all the problematic data using Overpass
It is possible to extract all objects with addr:city added by the particular user using this Overpass query.
Resulting features
This data can be exported into JOSM via remote control for further inspection and cleanup.
Fixing data in JOSM
Once all the data is loaded, we need to select only those objects or features that have been incorrectly tagged with the addr:city and addr:province. Since we know that the tags are valid on building ways, we will use a filter to select such tags on anything that is not a building way. We can use the find dialog (ctrl+F or cmd+F) to look for exactly this.
Find all objects tagged with addr:city and not a building
This selected 3,989 objects from which the tag can be deleted. Just select and delete the tags.
As a bonus got to also cleanup duplicate nodes using the validator.
Upload with a descriptive changeset comment and all done!

Actually,
addr:citytag can be found on address points: nodes without any tags besidesaddr:*. These are pretty common in Europe and a lot of other countries where detailed imagery for tracing building is not available.由 manings 於 2016年06月24日 12時50分 發表的評論
This is obviously wrong in the Philippines. Thanks for fixing @planemad!
