The only problem is that a spammer could "query" it days before it will

I think we need some "official" data like the domain's creation time: at

I recall reading about a scam used by registrars to buy up large blocks of names, then cancel the purchase and incur no penalty, then buy them up again, over and over, to hold them off the market at no cost. How would you detect such a thing?
