I think that the difference is that there's a way to get to Yahoo and ask them
WTF. Whereas the guy who mass downloads your site with a script in 2 hrs you
have no recourse to (modulo well funded banks dispatching squads with baseball
bats to resolve hacking incidents).  I also expect that Yahoo's behaviour is
driven by policy, not random assholishness (I hope :), and therefore I should
expect such incidents often. I also expect whinging on nanog might get me some
visiblity into said policy and leverage to change it! </dream>
