BOGON Announcement question

[Jason Lewis]

I'm seeing this announced at CIXP
Collector: CIXP
Prefix:   128.0.0.0/2
Last update time:   2007-04-27 07:36:30Z
Peer:  192.65.185.140
Origin:  29222

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.
