I'm sorry, I may be shocking someone here. But Youtube is a site apart from the Forum. This person has downloaded a roller coaster of a game for free, he made a video on it, totally different than the original creator, it is in his right to post it and do what he wants, credit or not the creator, since even if the content of the video is the same, the video itself is different, no pursuit is possible as much here on this forum as on Youtube. Indeed one can take for example a unboxing, on YouTube we see hundreds of unboxing videos of object like the GH5, the first user to have made an unboxing more right than the others? The answer is no. He will have no pursuit on the part of Youtube. For Youtube a real video steal of a user is like example; It downloads the original video through various tools available on the internet and rest without touching anything, the yes there will be pursuit for steals. In our case this is not the case and thankfully because think back to the example that I gave you above on the GH5
