[OSM-talk] "Stadium" map roulette challenge causing issues

[Andy Mabbett]

I have found several instances, on different continents, such as hris
example (since fixed):

   https://www.openstreetmap.org/way/521815946/history

where the tag "wikidata=Staduum" has been added to an object by
someone apparently using this Map Roulette challenge:

   https://maproulette.org/browse/challenges/36396

I am unable to determine why, or whether the challenge is in some way
misconfigured, but with over 5000 objects awaiting attention there,
the potential for damage is significant.

Is a bulk revert possible?
