Honestly, I don't believe the 80/20 rules applies here.
Until all transit networks are willing to strictly filter their
downstreams (and themselves!), if there is any unused space (note I
said "unused", not "unallocated"), the miscreants will use it. They
are not going around saying "oh, damn, there are only a few /8s left,
we better stop!".
Filter your bogons. But do it in an automated fashion, from a trusted
source.
Of course, I recommend Team Cymru, which has a most sterling record.
Nearly perfect (other than the fact they still recommend MD5 on BGP
sessions :).
