That was precisely my point!  If an upstream isn't filtering at their 
ingress (or their egress) the optimal place for me to filter is at my 
ingress.  Of course I'd rather have something akin to inter-domain 
pushback or FlowSpec, etc..  But you can't control how, or assume others 
will act on that.
