For me it’s less about bandwidth and more about not having to worry about building/ maintaining ratio. It’s just one less thing to think about.
I love seeding so I thought private trackers would be for me, but it’s so hard to go positive when EVERYONE is trying to. Yeah, there is freeleach but then I was downloading a bunch of stuff that I didn’t want, just for the sake of it.
Depends on the country though as well. Its probably pretty easy to figure out for big ones like the USA, but in smaller countries its often a mess…
