I think what you need more is a strict *import* filter on your side - have 
them register their routers in one of the IRRDBs (I assume you're in ARIN 
land, so in the ARIN IRRDB), and build the prefix list on your side from 
that source.

Of course it's preferrable if the downstream ASes only export what they
document to export, but it's absolutely necessary for upstream ASes on
that level to very strictly limit what they accept.

USENET is *not* the non-clickable part of WWW!
