I took a look at the sample hashes you posted here:
https://forum.defcon.org/showthread.php?t=11476
http://www.freerainbowtables.com/gethashlist.php?type=ntlm
Actually, it appears that they were user-contributed (right?), and most
of them (at least the easily crackable ones) are LM and not NTLM
(despite of what the message and the link say) - although it's a mix of
both types, as well as some others (plenty of raw MD5) and not valid
hashes at all (well, not produced by hashing a password, so would be
extremely difficult to crack).
I doubt that the hashes you'd use for the contest will be similar to
these, or will they?
During the contest, will it be OK to publicly share tips specific to the
contest hashes - e.g., recommend specific JtR settings on john-users?
