You’re right, it is worthwhile getting some clear guidelines on the help pages.
We’ll coordinate to get this together soon.
The initial purpose of this tool was to prevent unhelpful imagery. While “unhelpful imagery” can be ambiguous, there has long been an implicit understanding that Mapillary is a platform for street-level imagery used to derive map data. Therefore imagery of people or indoor environments is discouraged.
Mapillary is not well set up to handle indoor imagery. Firstly, because GPS does not work well indoors, so images need to be manually placed. Secondly, because Mapillary does not distinguish between indoor building levels, so there is no mechanism to give the vertical location of an image in a building with multiple levels.
That being said, I can see the real value in use cases like AED mapping that was mentioned.
A good starting point is for us to clearly define what images are unacceptable on Mapillary, in addition to what has already been described in our terms. We can then continue to discuss some of the ambiguous situations at the margins.
