You should've seen the email storm and panic created when I prepended  
an AS to avoid a blackhole.  I got the right people interested in  
talking to me at least, but boy-o-boy were people confused about what  
I was doing.

I guess the problem is that AS PATH is overloaded and people forget  
that the primary purpose is loop-avoidance.  Everything else is  
secondary and much like reading Received headers in SMTP mail, you  
really should take everything after your direct neighbor's AS with a  
grain of salt.
