It would be cool if we could set up some challenges in MapRoulette for this…
These aren’t necessarily ‘no name’ issues, but could also include missing streets by comparing external data:
I think I’ve figured out an Overpass query that’ll return unnamed streets that align with the existing CityStrides street query … I’ll post a MapRoulette link soon - if it looks usable, we can create one for each state (I can test it at the country level as well).
Massachusetts streets without names Oof 
over 100k way records without a name (and still counting). This is also using the existing query that decides whether or not to bring streets into CityStrides - so this might help point out other tags that should be ignored (like highway = service).
I’ve done a garbage job on the description & instructions. I’ll try to get around to updating those soon.
