Number of IP's currently known to have 69/8 filter issues: 299
Number of /24 networks's currently known to have 69/8 filter issues: 261

And it's probably actually not that bad anymore.  It seems a bunch of the 
IPs that were reachable from our old ARIN space but not 69/8 aren't 
reachable at all anymore.  Back in late 2002 and early 2003 (when we got 
ours), 69/8 was much worse.

Looking through the archives, it seems that first number was initially 
about 1000 when we got our 69 space, and when I announced 
http://69box.atlantic.net/ we had:

Number of IP's currently known to have 69/8 filter issues: 683
Number of /24 networks's currently known to have 69/8 filter issues: 511

So the half life of outdated bogon filters appears to be about 2.5 years, 
but if you really bug people like I did initially, you can make much 
better progress.  I basically picked the largest, most important looking 
networks and contacted them manually via email and phone.
