Youtube won't care for your video unless if he detects that :
Your youtube channels are fake and no owned by personnal, if so say goodbye to all the YT channels with this video.
The video you post and repost has no real content or it's spam or advertising. Anything that Kind.
If you want to play it safe, make sure that YT channels are real and their not making Youtube algorithms doubt in it.
All in all, you should cocentrate on the time spended on the video not the number of video repeated.
Best luck
