Think you’ve missed the point a bit of OP’s comment. They’re asking not how the end-user is protected from copyright claims, but how the debrid service itself is.
That strikes me as really out there. I think the reality is that there’s a lot of people into CP sadly – as an absolute but not relative number – and you don’t need many out there to have a prolific amount of content, which we know from our own special interest cases.
This is what always unnerves me about privacy tech. I always feel the pull of using high level encryption with whatever I’m doing – file storage, communication, etc – but a part of me is always saddened at the same time with how much abuse is effectively facilitated by anonymity and privacy.
But as the horrors of the dark web have shown, it’s a battle that law enforcement will never win – our most effective weapon as a society against CP and related abuse is Chris Hansen (I shouldn’t joke) …is engaging with and changing the material causes of this phenomenon. There will always be tools for sickos; the challenge is to prevent people from becoming as sick as they are, and when sick, finding ways to prevent them from abusing others.
