Roeland,

The last time I checked, AS65535 (picked for obvious reasons) does not
have a transit contract in place with my company and as such, has
absolutely NO grounds to sue me if we choose to blackhole 
routes to them
at our borders.

No transit contract -- no guaranteed transit.  It's just that simple.

The operative would that I used was "can" and not "will". However, you
don't discount my statement about blackholing creating artificial
outages. I am proposing a more surgical response to the smurf threat.
One that in no way creates outages and may be more socially acceptable.

You also missed the point that a IP-block can pass the netscan.org test
and STILL be a smurf amp via it's subnets. The subnet bcast addrs aren't
hard to find.
