Sometimes, it's appropriate, as the people who could do something about the problem are here, or reachable quickly through here. The prospect of being shamed before the HN community is probably a very effective motivator for companies who've been engaged in hinky behavior to clean up their acts, too.
But the simple fact is, HN isn't your mommy, and it isn't the police; we aren't here to hold your hand, and we aren't here to fix your problems for you. People are coming here, crying that "someone on the internet was naughty!" over increasingly trivial bullshit like this, and I, for one, am finding it more and more a waste of time and bandwidth.
