I recently got a 4k TV and so I'm really wanting to watch movies in 4k. They take up so much space that I can't really put them on a flashdrive to watch, and as there aren't any piracy streaming sites with 4k content I was thinking about using an old PC to make a media server on either plex or jellyfin.

My parents, who are okay with piracy streaming (fmovies.to) and even downloading are convinced that if I upload to a personal plex server, that it would be the same as someone uploading to a torrent website somewhere and that I will get swatted and sent to prison.

Is this a valid concern, or is it perfectly fine to upload pirated stuff to plex? Is there any chance at all that you could get into legal trouble for uploading your pirated media on plex?
