I’m unsure of HNs stance on piracy so I’m hesitant to post any specifics. For a single account, key words to search for are “plex shares” or “emby shares” and if you want to run your own server instance to be able to invite others and change the metadata (fix mismatches and choose specific artwork , basically) the keywords are “plex appbox” and “emby appbox”

You’ll find that the majority are on Discord, so you’ll have to get in on that platform, but it kind of works better as it’s easier to keep track of the different offerings, switch if needed, etc.

If you get really stuck, let me know a way to PM you and I’ll give specifics
