my film is being trolled

My film is being targeted by someone called sammie lei. I have had to remove 'cast' members over the past 2 days as well as inappropriate picture she has added. She has nothing to do with the film and is targeting the film as it contains cast members she has been trolling for a year. The police are involved in the trolling issue and if it continues I will report her to the police for this unless she is stopped. I have always been nice to her and asked her personally to stop this to which she has added more that I've had to remove. Images attached are the things I've had to remove.
