If anyone's unfamiliar with this client, it's been around a long time, and was previously named Vuze (and before that: Azureus)!
Tis been under active development by the two main devs for all these years. The adware crap was removed from day 1 of the fork and it's a really solid (and featurefull) client. Highly recommend. Also does I2P.
The absolute best feature is Swarm Discovery and Swarm Merge, which lets you find identical large files across different torrents and cross-seed and merge said torrents while downloading both. With Swarm, I've been able to download torrents with <1.0 availability - completing both torrents and become the seed hero. And this was before it supported the v2 BitTorrent spec (which gives you individual file hashes).
I still use qBit for my *arr automation but BiglyBT is always there for everything else and as a great backup client.
Suppose one way around it would be to rent a cheap VPS in the UK and piggy back off the connection?
Otherwise, there's a s2 'NORDiC' version going around which is actually in English audio - just with various scandiwegian soft subs, so it's defo out there. DM me if you still struggle to find it.
