Isn't this legally the case? There's a random place on the internet and people upload details. Not payment info, and I honestly am not clear on how much the rest is protected (USA). This is exactly what Zuckerberg called people "dumb fucks" for, and I don't think anything (legally) has changed.
I'm on your side as far as the "why the hell is this the case", but I think this is the world that (USA and others) live in.
