Bet she wouldn't know better if that url were hidden inside an

``<a href="...">http://www.amazon.com/deals/free/</a>''

url, now would she? Never seen a spammer do that before..

you would have to not only capture the IP, but all the domains associated with that IP. Unfortunately, the load against the whois/dns database servers might be a bit more than we can tolerate.

DNS caching would become extremely important.
