Bad for whom? Only for the sender? Does this sender have rights which should supercede the property rights of recipients and of infrastructure owners?

As an infrastructure owner, the important thing is that if you're going to announce reachability, it should be real. If you blackhole stuff in the middle of a netblock and distribute it as an untainted netblock in your BGP, you're depriving people of clean routes. Other than that, exercise your policy to your heart's content. -- Jeff Haas NextHop Technologies
