Torrents are people sharing files with each other, uploading and downloading. Stremio downloads, but never uploads. And now it doesn’t want you to know who’s using it, because people kept banning it.
This client is already extremely popular. Before the spoofing update, it’s mis-identified as TorrentStorm 0.0.0.8 in qBittorrent. It makes up half the peers on a lot of my torrents. Have you checked?
If you use a debrid service, you’re okay because the debrid service just downloads the file once and caches it for everyone, and you pay for the bandwidth to download from them. That isn’t excessive leeching, whether they seed or not.
It does dominate my personal bandwidth. You’ll notice if one of your torrents is on their app. You’ll be uploading all day and it’ll fill half your peers list.
You got downvoted, but some researchers discovered this works on some cellphone networks. They only look at what the site calls itself and not what the site actually is.
