Funny you should say that. A few months ago I had a 'student' approach 
me wanting access to my BL database. I requested a copy of the ethics 
approval / research proposal (as a postgrad would have) and they 
disappeared.

Though the strangest thing I've seen was just the other day.  I 
firewalled a whole /16 for doing trickle-scan at 3 queries per second of 
the entire IPv4 space against my local BL (which are updated from 
spamtraps every few minutes and expired hours later).  No idea what they 
thought to gain from that set of NX results.
