If this is true, then why do the european NAP mailing lists (which push IRR
filtering) have an almost constant stream of "oops, our customer announced
everything to us and we leaked it".
Filtering peers is not the way to go. Filtering customers and "trusting"
peers to do the same is. (Whether that trust explictly mentioned in a
peering agreement or whatever).
Just a shame that not everyone filters their customers. And although it
has been a while, I know I've seen a route-leak from 6461 at AMS-IX.
(Probably last year sometime)
