Responding to you would require moving right away from the guidelines for HN so I won't. But it would be best if such links were not provided in the first place.
Is this collection of information on non-users even legal?
It is not okay here in Sweden (PUL) and as I understand it the same laws apply in the whole of EU.
Is this a US service only?
No more bizarre than Ent Rails (you know, railways for Tolkien Ents) is the same as entrails in English.
Just as you can't actually say inriver and pretend it means something in the river in English, you can't say inälv and mean something in an älv in Swedish. But as a pun it is okay, everyone gets the word play.

I think "in-river" is pretty acceptable in speech, and mildly so in writing. If you said there was an "in-river pool", I wouldn't bat an eyelash.
That said, the relation between the adjectivizing(?) morphemes "in-" and "at-" (e.g. "at-home bar") and their corresponding prepositions is weird and makes my brain hurt.
One should make a graph showing man years put into each part and see how big the kernel would be compared to the wmware parts. It would most likely paint a completely different picture and also show the importance of that 1 percent of the plaintiff.
Why give any kind of credit to these idiots?
Don't blame some religion for what idiots do, don't blame people from other countries for what idiots do.
Education and general life improvements can help idiots to become non-idiots. Closing borders or checking body cavities seldom help with that.
