Your video doesn't show any information about your account? Like the rank or anything else? If your video is purely of scouting, then they could think that you could have gotten the footage off some random video in the internet. People upload these kinds of stuff all the time after all. This is why they ask things that only you should know in the first place.

You could try sending it to them, but I won't hold my breath. What you can say with it is the truth which is:

I don't have evidence other than this video, but this is a video showing my scouts. 私はこのビデオ以外の証拠はありませんけど、これは私のを勧誘するビデオです.
