So which ISPs are confused?  Bogon's don't spontaneously occur in
BGP.  Some ASN must originate them, and ASNs must pass them to
other ASNs.  BGP helpfully includes the ASNs in the path.

What should be done about ASNs which repeatedly announce false or
unauthorized routes?

Like: AS 15188 (rogue) ?

It appears this AS is on the tail of

7018 10910 12124 15188
701 10910 12124 15188

AT&T (7018)
InterNAP (10910)
Thorn.net (12124)
UUNET (701)

Who isn't filtering?
