Here I go being silly again, but how about people take responsability for their own networks and filter properly at their borders? All this talk of how to enforce things is pretty meaningless when you have countless members of NANOG itself half-assing their own networks and complaining about other people's.
Because this is only half the answer. I always filtered my announcements, was careful to register all the address blocks I used, and was very responsible for my own network. It had no effect on someone else hijacking one of my addresses and announcing it through a large ISP's route tables. I was effectively cut off the network not because of anything I did, or could control. Worse there was little I could do to fix it. I had to wait three days for the large ISP (with whom I had no direct relationship) engineer's to decide it was worth their effort to stop the source of the false announcement. Unfortunately this is not a unique occurance. Cable&Wireless, Sprint, AT&T and UUNET have all had portions of their service knocked off the Internet for various periods of time due to bogus announcements. Until other ISPs fix their policies, I can knock your network off most of the Internet, and there is nothing you can do to prevent it.
