Mapy.com does this and I often see and resolve these notes on streetcomplete. It's nice setup, they provide a suggestion and location, it takes little effort to check if you are walking by and just reply to the note. Some enthusiastic editor (can be you back home, but it's annoying to do on a phone screen) then can make the edit and resolve the note.
> Example of a valid and useful note can be "a new road was constructed here" or "this shop is closed and does not exist anymore".
