Looking at one log, the most persistant announcer of bogon space is
AS 4554 (Bill Manning), Net 39.0.0.0/8.

I don't know Mr. Manning's intentions, malicious or otherwise.

I don't do peering anymore, but a peering agreement did include a
paragraph concerning route filtering.  Sorry, but it got translated by
the lawyer along the way.

  "The parties shall use through the Interconnection Point only Autonomous
  System Numbers, Internet Protocol addresses, or other routing
  identifiers assigned or delegated in accordance with IANA, a mutually
  recognized address registry, or other mutually agreed procedure to the
  party or its customers. The parties will use reasonable efforts to
  screen routing identifiers not in compliance with this paragraph from
  distribution across the Interconnection Point."

???? Well, I can't think of anything that unenforcable.
