I believe hosting torrents or files ripped from open TV sources is not illegal, if the channels in Japan were coded and needed to be decoded I would understand if it was illegal, but isn't. It's like you can legally possess recorded programs of national geographic.
Majority of stuff on websites lie nyaa is the ongoing stuff. It's not even seeded long.
Bakabt is hosted outside of usa/japan and is pretty much safe in that regard.
I'm not sure what measures HS took to be untouchable but they too are not really breaking the law by hosting rips. Especially when you have free access to it at the source.
Those measures are a joke, and their offer is more of a joke.
I have more anime on DVDs than they offer.
