Plex Security Incident

You have to be a fool to use Plex, not only you are pirating, but also relying on a 3rd party company to handle your authentication. They already got hacked multiple times, only a matter of time till there is some copyright law enforcement event too.

If you really have to do it, use Emby or Jellyfin. At least those options are fully self hosted.

Plex has their own streaming-with-ads. And one can load it with whatever you want, including home movies or DVD backups.
