Because they are being filtered :-) If more people filtered bogons, the
"ROI" would be even lower. Although it is clear that bogon filtering is
not a complete cure for spoofing, it does help and it also helps for
some spammers.

The only negative effect of bogon filtering is not-up-to-date filters,
which is why we have written this draft that will expand the
applicability domain of bogon route servers and other filtering schemes.
