I don't know if they still do it, or if their old "Abuse/Security guy, 
Travis Haymore" is still around, but above.net had a history of null 
routing "destinations they didn't like", which meant if you were a 
customer (even a multihomed one) and sent them traffic for those 
destinations, you wouldn't get there.  Getting the list of null routed 
space from above.net was not trivial.
