With the availability and ease of use of Seed boxes, this feature is kinda moot. It doesn't even cater to power users any more because they've all moved to seed boxes a really long time ago. This just leaves semi-serious individuals that want to take the risk of torrenting on their private internet connection.
Yeah I'm not a big torrenter but sometimes I want an old show that is only offered by a few seeders. And then most of them don't work due to this.
If you just want to grab the latest blockbuster it's no problem no.
I've never thought of getting a seedbox, i always thought the amount of storage required would be prohibitively expensive for a VPS. Also, I'd still want to use a VPN so the VPS provider isn't the only protection layer.
You'd be surprised how much storage space these seed boxes provide for very little cost. And these things aren't VPSs anymore. They're glorified SaaS products that give you Netflix streaming in a box, for less than the cost of Netflix itself. I would recommend doing a "reddit" search on the topic and you'll find many many recommendations and ideas.
Personally, I do it because of the "Netflix effect". Movies and series don't exist if they're not on Netflix (or your chosen streaming platform). And with my kids growing up, I want them to see the good shows and movies I grew up with just as they share the shows they enjoy now with me. I can comfortably say that 99.9% of that media is never offered on Netflix.
Everyone wants to seed, so it's over saturated. Thus you won't be hitting the limits any time soon, and if you get close you just manage it with limits.
But to answer your question, for 25TB I've seen packages that cost 20euro, which is pretty much the same as what Netflix premium charges in the US.
I'm not gonna advertise them here. Next thing you know the wrong person takes an interest in this area of the internet and spoils it for the rest of us.
Trust me, I looked at the page of my provider just now and that's what they offer.
