[OSM-talk] Recent spikes in the use of road key

Looking again at the chronology, we see that road=yes is often combined with the key highway. These road=yes could be removed.
This Overpass query shows 706 such ways.https://overpass-turbo.eu/s/14vp

Seems to proceed in the same extend with the key road_name.
 All values are in an Asian script, I presume Chinese, geograhically concentrated in Taiwan and Melbourne, Australia.

Just the key "road=*", search for road in Taginfo tab KEY.
 In Taginfo I searched for the key, got a long list with all kinds of keys containing the word "road", then selected just "road" from the list returned by taginfo.
 
 
If you go to chronology tab you see the spikes very clearly.

  Hi Bert, 
  please, give us more details about the tags you spotted in taginfo as not valid, not using the highway key. 
  From there, it should be easy for us to propose an Overpass query.

Dear all,
 
I was recently working on some local proposals and, through taginfo, saw some recent spikes in the use of the non approved and discouraged use of the road key (should be highway).
 The spikes, due to their amount and short time-frame in which they appear seem to be indicating unnoticed mass or automated edits.
 Do they need closer attention / investigation and action to revert ?
 
 
1. Jan 2017 - spike of +-500, seems to be reverted by +-300 by Mar 2017
 2. Mar 2019 - spike of +-400, not reverted
 3. Sep/Okt 2020 to Feb 2021 - spike of +-800, not reverted and continuing at a worrying rate
 
These 3 spikes together make up 3/4 of the total use cases of the road key.
 
 
Would appreciate some help with taginfo / overpass trubo / other tools to get more insight on the phenomena.
 
Greetings,
 
Bert Araali
