I don't see why most of them haven't published information about their 'customers'. I remember a few years ago one torrent site that was in trouble doing that. It made it too expensive to sue them as whoever tried to sue would have to also prosecute everyone who used the site (because they all broke the law). It would just drive costs to high and publishers would spend more finding out who downloaded what, than they would save.
I dunno, maybe they can get round that.
