I think it could be automated bot. Clients can fetch these data and do things like blur the content if trusted profiles flags things, relay/blossom operators can monitor them to remove unwanted items, but I still have to see that used in the wild. But apparently someone is using it, because there was plague of post promoting illegal kind of porn which got reported left and right (by me included) and it seems that nowadays there are none. Still, you can't report a report for being foolish...or can you? 🤔
