Yes, the person who started this thread didn't notice a few things like the fact that Blake said that instead of being in the White Fang, she would dedicate her life to become a huntress, meaning that she left the White Fang in the Black Trailer.

Also, there is no proof that Adam left the White Fang or that he is the leader.

Let me close this thread by answering the original question:

Were Adam and Blake still part of the White Fang in the "Black" Trailer?

Yes, they were until Blake left the White Fang during her trailer but Adam wasn't aware of this since he tries to reach her like saying: "Wait, don't go!". Adam is still with the White Fang but Blake left a few months before episode 1 and decided to apply to Beacon in order to become a huntress and protect people instead of tormenting them like the White Fang does.

Also, it's completely out of the question to think that Blake have been a stray for years considering that she is a teenager and she would have grown a lot if she left the White Fang years ago. Also, by the time the Black Trailer took place, Blake was already a badass so she doesn't need Adam to train her anymore. She has teacher now.
