Thats rediculous.

Every time you setup a peer without a access-list (and don't everyone go
saying you don't do that!), you're trusting the other party not to be
AS7007.

It's commonly accepted that if you announce a route, you can carry the
packet to the intended and correct destination. Existence of the host is
irrelevant; 'owning' (and I use that term loosely, ARIN) the block and
delivering it to where that netblock exists. If said 'owner' wants to
block, drop, blackhole, whatever the packet, then it is their option.

I applaud Above for trying to cut down on the Spam. But, shouldn't that be
up to UU to do, since this is a UU customer?

enduser isn't subscribed to a service that the Above AUP applies to; also,
I doubt that UU subscribes to Above's AUP as well.
