would loop detection be a thing that could work or do you not get the stream at the server at all? The client could tell the server if it detects a loop maybe?
The stream is completely P2P so the server doesn't have the stream it just hostes the app. *Not the developer*
The server does do book keeping so it could take a note of a loop detection from one of its clients and report it to other clients. It would mean though that the dev would not only have to develop loop detection (hash each image, keep the most recent hashes (maybe only those fitting a certain filter that matches only one in 30 pictures, get full pictures that match a repeating hash to be sure?) but also develop rogue loop report prevention.
