Read the Plex TOS & the Privacy Policy, they have some pretty hard, & user-favorable stances on how your data is used. They specifically say that your User Content data will ONLY be used to the purpose of providing & operating the Plex Solution.
They even advise you to be carefull when using 3rd Party Integrations
16. **THIRD-PARTY PLATFORMS & NETWORKS** .
Certain features allow you to synchronize your content across third-party platforms & networks. These features will enhance the performance of the Plex Solution & allow you to better integrate & harmonize the Plex Solution with information stored on or used with third-party networks. Using this functionality typically requires you to login to your account on the third-party service, & you do so at your own risk. You should always review, & if necessary, adjust your privacy settings on these networks & platforms before linking or connecting them to the Plex Solution. You expressly acknowledge & agree that Plex is in no way responsible or liable for any such third-party services or features.
You missed a lot of important parts there.
Exactly, Plex has it’s own source for Metadata, unfortunately there is no way to contribute to that source, But when Plex user your Filename to find Metadata it uses that to see if it has it. If, after that, the Database is smart enough to try to find it, then assuming it may be called for again make a record in IT’S OWN DATABASE for that title. That isn’t using your data anymore. by that point I bet the information about the filename that called it isn’t even there anymore, just the data about that title.
Not tied, it refences it, then releases it back into the wild. It only used that to look. I’m sure you’ve had things mismatched before. After that match Bweezy's Raunchy House Party.mkv no longer exists in the system, instead the system has House Party (1990) TMDB-ID:16094 which it thinks was what you were looking for, nothing else. If House Party didn’t exist in the Database they then decide to add House Party (1990) TMDB-ID:16094 not Bweezy's Raunchy House Party.mkv to their Database. & Plex & it’s Databases ONLY used your data (Read: The Filename) to do just what they said the` identifiers for your Personal Content were used for the sole purpose of providing metadata back to your personal Plex Media Server
See Above This is exactly what I was talking about. The only difference being that in this case the Results weren’t House Party, which is certainly in the Database already, but something that wasn’t there that the scrappers went out to find, returning something that was linked to a service, but didn’t have the tags used to restrict it. So again your file Bweezy's New'd Chicken Dance.avi didn’t return anything on their DB, so the scrappers found somewhere Famous Celebrity Jenny Eat's Chicken While New'd & now the data from Famous Celebrity Jenny Eat's Chicken While New'd has been added to the database. But nothing about your file is in the system.
I know I’m Troll Feeding answering this last one but I gotta say it… It’s not stealing your data. It’s the toll to cross the bridge they built.
