Ok, so, I got the unlock requirement open, and I know I have to deal with 5 black Market, but, I'm already at 1/5 and now after having sold some quest materials at two different markets (the same one I used first time, then one I haven't used before, both before and after abandoning the quest and having the materials marked as stolen) I'm still at 1/5. So I have to empty my cargo hold of illicit cargo per transaction, or am I missing something?
