BOGON Announcement question

[Jason Lewis <jlewis () packetnexus com>]

I'm seeing this announced at CIXP

My question is, why am I not seeing more issues because of the 
announcement?  Is it just not propagating out of the exchange?  It's 
been announced for a few days and only seems to appear at the exchange.
