Reddit [0], for one. I'm beyond sure that Discord has at least one community for this as well, but somehow piracy feels morally okay compared to Discord silo-ing off areas of the internet - ergo, I have no link, sorry.
/r/PlexShares! Lots of options, they all have largely the same stuff. There are also more specialized ones if you want anime, Bollywood, K-dramas, etc.
Just shop around and find one with a free trial. It's not very automated, so you'll have to chat with them over Discord, but once it's set up it's completely hands-off. Good luck!
