I closed this question the other day:
It got reopened. I just wanted to move the discussion of why over here instead of muddying up the comments on the main site.
If you think this question is a good question, can you tell me why?
I don't think it is because there is no way to tell what the correct answer is... There are currently even answers up there that completely disagree (yes, you are liable. No, you are not) and no discernible way to discover who is correct.
I understand that this is a legal question about money (debt in this case) but I don't think the focus of the question is about money at all. It is just about the legality of whether the person owes a bill or not. To me it doesn't seem like the 'experts' of this site are able to answer that question ('experts' on a legal site might be able to).
