p.s. I dont care who the particular couple is. It could be a bowling league and I would still expect to know who it was.
If you don't care, why do you expect to know? Are you saying you don't care where that info comes from? To some people that's very important, and as a business or third party you have to respect their wishes. I suppose that policy will change when some jury awards damages because some third party didn't disclose a name. I can see the lawyers salivating now - they win if you do, and they win if you don't.
