I'm surprised people are so positive about this. Not that I'm negative about it per se, but I have quite a few issue with it. To name a few: 1): Doing high-volume WHOIS queries can come to bite you in the butt. NETWORK SOLUTIONS, LLC., for instance, specifically states: "You are not authorized to access or query our WHOIS database through the use of high-volume, automated, electronic processes." People can ignore that, I reckon; but at their own risk. 2): Blanket assigning of spam-scores to a every "young" domain, effectively brands every new domain owner a likely spammer (or if your score were so low that it doesn't matter, then this use of this "Domain-Age" test is useless to begin with). I see a potential for false positives. 3): WHOIS data tends to be bulky. Not sure I care for such huge overhead. "caching" here won't matter, because, as the OP pointed out, these domains just have a very short life-span. You'd essentially be making WHOIS queries all the time. I'm quite open to the possibility that I'm missing a vital concept of this idea that would allow me to see things in a different light; but for now, I think I'll pass. :) - Mark
