I’ve definitely come across “obscene” content. If you browse a live stream of what random people are posting to relays, it’s there. Worse, most clients seem to download media by default. Since media is stored on third-party http servers, your browser has to make a DNS request for the server and open up a connection to fetch it. If that content is illegal in your location … well, hope your ISP doesn’t have enough info to turn you in. 🤷🏼♂️
