Impossible to kick someone who shares a youtube video

i’m doing some testing with 3 different laptops and found out that if one of the guests shares a youtube video, and I kick him from the room, he comes back and the video doesn’t stop. This is very bad considering if someone joins the meeting, he can ruin the whole thing. is there something we can do as a moderator to have more control over this? Also, if sharing a youtube video can only be made by the moderator. Thank you!
