I can give you info about a provider that offers full F1 TV access for 20-30€/year, I've been using it for a few years now. It's great and you can easily stream it on any device. Send me a DM if you want more info
You might want to have a look at Usenet. Yes, it costs money but it's such a premium experience compared to torrents and you don't have to care about seeding etc at all
Just having a Jellyfin instance for family and friends. I have everything in h264 for maximum compatibility to avoid transcoding. All 12 seasons of Bones (2005) take up 800GB alone for example. A 1080P Remux movie takes 10-40GB
Radarr/Sonarr can't handle multiple versions of the same movie/episode, so a lot of people have a second instance for 4K movies (so they can have both a 1080p and a 4K version of the same movie). Also if you have a lot of anime it can be worth it to have a Sonarr instance configured just for that
If you are looking for German (or German + English dual language) content it can be very hard to find stuff on public torrent trackers and it's pretty hard to get onto private German trackers - but don't worry, there is a solution:
Usenet and the indexer sceneNZBs.com that specialises in German releases have got you covered!
Long answer: yes, but they are basically useless. Except for some indexers that cost money but also have a free plan where you are capped at like 5 downloads per day.
May I ask what I should look for in the log files to detect this (and so I can configure fail2ban correctly)?
