Yep I've been using it almost 2 decades with basically no slowdown, I have netflix which is bad enough and refuse to pay for any other streaming service so anything not on there I torrent, in addition to games a few times a year would be more because most large developers are trash but I not much of a gamer
The extra time it takes to find a magnet launch my client and DL is worth the money saved, anything popular has enough seeders to DL quick and anything obscure enough not to have many seeders you probably wouldn't find on a premium service at all, as is the feeling of getting one over on atrocious companies and the sense of smug superiority over those paying for 5+ services and still can't watch everything they want
It ain't going anywhere
Idk about stl trackers specfically but magnet links and torrent files for stl's under the physible category on pirate bay have them attached
