 Replace "is" with "has never to this point been".

 If we're trying to protect against some sort of security issue, we've been
 doing it wrong.

 And this proposed change would probably still be doing it wrong -- first
 because totally unloaded nodes will look good on their bandwidth
 measurements, and second because the bandwidth measurements are still
 gameable.

 If your adversary can run a relay on your IP address, that's bad news as
 you say.
