We're currently more than tempted to filter out all the "we're just too
lazy" garbage out of what we accept - like "nearly 4000 /23 and /24 in
216/8", and none of them are of any real relevance for us, sitting on
a different continent.

Rough estimation ("do not accept /23 and /24s from /8s that are on
other continents") show a reduction from about 155.000 prefixes down to
about 110.000.

Guess how much money that'll save...

(Yes, there are drawbacks.  BGP customers need to know, and agree, to
only receive a reduced table.  Connectivitiy issues might arise, but 
those can be caught by adding a static /8 for these netblocks towards 
our upstreams).
