BCP 38 would work. The problem is that many ISPs do not ingress filter, so I can use whatever unnallocated IPv6 space (2F10:baba:ba30:e8cf:d06f:4881:973a:c68) to SPAM and then go invisible and use another one (2E10:baba:ba30:e8cf:d06f:4881:973a:c68)
How do you plan to get the return packets? DNS bombing with forged address UDP packets is one thing, but anything that runs over TCP won't work without return routes. If the bad guy can inject routes, you have worse problems than lack of SWIP. (This assumes the target is not using a 20 year old TCP stack with predictable sequence numbers, but in the IPv6 world we should be able to assume that particular security hole is closed.) I expect bad guys to hop around within a /64 or whatever size allocation the ISP assigns to customers, but that's still easily handled by SWIP, or by subpoena to the ISP if they didn't get around to SWIP.
