Does anyone else have users watching the same content over and over?
I have a user who has watched Bedtime Stories with Adam Sandler 13 times in a month and I am starting to get concerned. I try to mind my own business with what people watch but when the stats say that it is the most watched movie and there is only one user that watched it, you start to get curious.
I had a buddy that realized rogue one put him in deep sleep in under ten minutes. He played it during the night on repeat for three months. His roommate was going nuts lol.
I had to teach my toddlers how to rewind their Barney VCR tape because I got tired of doing it myself. I am quite sure they wore that tape out. Kids do things like that. If there's only an adult in this house, they might be using it as background noise. I also know someone who leaves the tv on so their pets aren't sitting in silence all day long and have something to hear. One does it because if she doesn't have something going with noise her dog hears noises outside a thinks he needs to bark at them.
OP, you could just screen shot something and ask the person in a joking manner. Just show them the stats and ask to see their shrine to Adam Sandler...
Consider the fact they may be using a 3rd party application, like ErsatzTV or similar, to create a "virtual" tv station that just plays videos in sequence after being added to a channel.
You can always reach out to the user in question if you're concerned though. I generally wouldn't open my plex up to users unless I had regular communication with them anyway, but that's a personal thing I think...
Edit: Another thing to note is that, depending on the user's tech savvyness, they might not be aware that you can see what content they're watching. If you aren't close friends, it might turn them off the service to have an admin approach them about the content that you yourself are hosting. Consider this and really weigh whether it's your own business or not. And obviously, to be clear, you definitely shouldn't be charging for this service so make sure that you're not putting yourself in potential legal problems.
