StreetComplete can create Notes, too. [edit] I think that's default when a question cannot be answered.
For those not aware: On https://www.openstreetmap.org/ you can leave comments on the map, so called Notes (https://wiki.openstreetmap.org/wiki/Notes). It's like bug reports but on a map, with comment thread. Local mappers look at those. Or that is the idea, I've seen notes open years and others resolved within hours.
The answers with new information are useful for local mappers, even "this shop no longer exists" answer (examples https://www.openstreetmap.org/note/2659780 , https://www.openstreetmap.org/note/2641050) when asked about opening times. Many notes need a local mapper to verify (visit the place, find secondary information).
