Nine digit zip codes

[Bob Sneidar]

Right, but not a lot from one place. I think their acceptable use would be under 30 or 40 hits a day from one IP, but if they get thousands, I think someone might contact you. They have some kind of published Acceptable Use policy on the site don't they? If not, then I guess you are in the clear.
