My go to strat. I already have a bunch of torrents so when I join a new tracker I run cross-seed, then I set up autobrr and grab the internal releases for new shows/movies.
I also have some script to auto-upload to some trackers.
Sadly you’re right about RED, only viable way to get upload on RED is to upload content
Buy a cheap Xiaomi phone for like 50 bucks from your local semi-sketch phone repair shop and use this: dumper. I had an Android I bought to try modding it and then I found Dumper and it worked well.
Fyi, there’s many scripts out there to make WEB-DLs from many streaming sources, I don’t recall the self-host git site though, perhaps a kind fellow will link it.
You can import existing, but it’s a pain todo so. Not much has changed in general I presume.
