Serving randomized image suggestions to users for editing runs the risk of serving an NSFW image (to an inappropriate user / in an inappropriate context).

When our NSFW image classification service (T214201) is productionized, incorporate it into the image suggestion algorithm and avoid serving suggestions above a reasonable (TBD) threshold.

Alternatively, we could simply include NSFW likelihood scores in the response, so that clients could choose how to handle them (say, by filtering out those above a certain score for a user who has not elected to receive them).
