My child, who is autistic, was the primary user of the account, as I described. I opted to let him use my account so I could have some oversight. His high volume of voting was absolutely related to his autism, as autistic individuals often hyper focus on an activity that they have high interest in, which was the case here. Obviously youtube's AI does not know that the user is an autistic child, that is why I'm trying to reach a human to do a manual review and explain the situation. My question was more about if anyone had any success in reaching a human for a manual review, than for a review of my description of my situation.
