It's one thing for admins to say, "We regret inflicting the collateral
damage on all home users but we feel we have to to blacklist dynamic IPs
because of all the infected Windows machines." But it's just obnoxious
snobbery to say that all home users *should* be blocked.

What about some responsibility among blacklist operators? Why not provide
a way for users who pass some tests to register dyndns-type hostnames for
whitelisting?
