You can not appeal agian. If all you did was post the youtube link or the asker would be forced to watch it to get the answer, that is a violation. You have to provide at least a short answer and use the video as a reference.
This is because if the video is removed, there is no answer. Now if you gave an answer and the link, you have to look to see where the video originates. If with a group that is commercial (even if not selling in the video), that is a problem.
Lastly, remember that hits to a youtube video or a blog do get the person hits on their sites which can be considered commercial. Without the violation notice and the link, there is really no good answer we can provide beyond this. One thing to always do when referencing videos and webpages from a general site like youtube.
Always post that you have no interest or authorship in the reference. This is always good when recommending a site selling anything. It doesn't always work, but may help your appeal.
There is no process to appeal a failed appeal. It's meant to be a one-shot, and you're supposed to abide by the decision of the review. I suppose you could contact customer care and make an attempt to have it looked into further, citing the case number you were given.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
