Why don't you just post a link to the video(s) here, for everyone to see? Then maybe the community can make some comments about it. I also don't understand your first statement about not knowing the person and then switching it completely, saying that you're working with him. Can you elaborate on that?
This is the point, if he had said from the beginning to work with him, it would have been a doubt without feedback but since he said before he did not know Russs512 and after a week he not only declared that he knew him but also he is working together... (leads to thinking, they are the same person or they are evading the ban as a team)
This not a correct behavior in my opinion, of course, I can be wrong if the community thinks that the feedback is too much for this case I can remove it.
I would be happy to know what the other DTs think about this case.
