Sure, the router is dropping the traffic like mad, but it's As I've seen it, Tier1.net and Tier2.net don't really care until it burns up all of their available exchange/peering bandwidth with the outside world. They're too profit driven to notice the impact they're making on others. If it were not so, or they actually had the headroom in bandwidth *AND* router CPU, they (AS174 for example!) would implement ingress filtering when at minimum, a peer asked them to. AS174, look back to 1995 when I was (stupid for being your customer to start with) taking 45Mb/s at each of your borders and you *REFUSED* to block it there AND/OR at the router we peered with!
