Which part should be in the wiki?
If you want to find more mistagged features you could use overpass-turbo, which gives you SQL-like interface to get data out of OSM.
Or you could use external tools like Osmose or in iD and RapiD open "Map Data" side panel and turn on Osmose, ImproveOSM and KeepRight validators. (but be careful about fixing some of those problems 😉)
