There is no easy way to fix BGP. If you got your way, then how would you ever 
allow multihomed sites?

Just track them down and
a) get them to fix it
b) get their provider to filter their incoming announcements

If all the ISPs, both end-node and traansit, did perfect route filtering this 
would never happen. It's not likely to ever be perfect, but it can be much 
better than it is now.
