I'm assuming this is a more or less universal practice. If I think of the road on which I live, there are three or four houses that have the same postal code; I don't think it's more than that. So once you've put the community back in, you've put the address back in, effectively. It seems to me I could figure out where a person lives from that.
I'm just wondering why you don't just put the address back in. Why don't you just get rid of the...?
I assume that's your objective, right?
