Yes, on the phone actually by the women who contacted you in the first
place...

I can live with that. But stop announcing it...

What I would expect is that you would choose between two things:

1. you blackhole but do NOT announce those netblocks;
2. you annonce AND deliver traffic to every host in it;

Don't you agree that announcing means delivering traffic? Especially for
customers.

Because Above.net seems violates the first thing needed in
internetworking: trust. If you tell me you will deliver traffic to $blah,
I think I may expect you to do so. That's my whole point. Nullroute as
much as you want but don't announce it on your border routers...
