ok the rules:
every week Saturday and Sunday can be done the duels
if you want to climb up for 1 position you need to win against your next rival
you can climb only 1 position on week
the defender decides about the place to fight and the method of dueling
if you want to try to climb up you need to tell that to the opponent 1 day before
if you didn't do the duel (coz you didn't be ingame or every other reason) you will fall 1 position less and the opponent will take your place
only lawbreakers can be in the blacklist (pirates, some mercenarys)
in duels no bats/bots, that mean clean fighting, WITHOUT CHEATING
if I forgot some rule please tell me
the Blackilst will be posted in the Events place 
And i cant defend as no one can challenge me - as noone is below me. Thats how i understood it so far. You can only engage someone that is one position ahead to me. If i dont engage i remain there where i am.
