Perhaps rather than arguing about whether we'd all get blocked by running this, it would be more productive to lobby a registrar to provide the data in rsynch-able form to URIBL or SURBL where DNS infrastructure could be used to make the data available for such a use. Maybe none will cooperate, maybe one will.
We can agree that 1. Querying whois directly is a bad idea if you have significant mail volume. 2. Whois data (namely, the domain creation date) can provide a hint that the URI might point to a spammer site. So, how can we get whois data without going directly to whois for every query? Bret
