Excludarr manages your libraries in Radarr/Sonarr. It keeps track of your library and checks if your movies and series are also available on a configured streaming provider. It can exclude the movies and series that are available on a configured streaming provider. But it can also re-add movies and series if they are not streaming anymore.
Edit; nevermind, while Radar reported it has deleted the movies, it had taken some time for it to actually happen. Please delete or close this ticket.
