Further on this example:
The delivery guy knowingly delivers drugs, it's written on the package, and the authorities told him to stop doing that.
Then what to do ?
Remove the license of that most specific delivery guy.
That's what they try to do (though it would be easier if the delivery guy would collaborate of course).
Not saying that blocking internet hosts is a good thing, but I don't see what else they can do, if the counterparty is not compliant :|
(DNS blocking doesn't work anymore as browsers provide circumvention methods by default, and blocking the whole BGP peer has too much side-effects because it blocks all the legitimate delivery guys too)
