"Black box is good if you're not particularly intent on being effective or the other team's flank is bad at playing the flank." ive seen plenty of good roamers do a lot of work against some of the best flanks, but ill agree with puff that it does force a passive style in some situations. it mostly works on teams where the roamer is alone on the flank (i generally try to tell my scouts to go do other stuff when i blackbox). i feel like a do a pretty solid amount against some of the best scouts, namely decent performances against mixup and 4g where i play alone on the flank. ive seen maela and mangachu have great plays against the best flanks too, but oh well. like gigglgglyy said earlier, if you value working the flank more than going for the med blackbox is a great choice, and i think there are maps where it is more important.
