Is there anyway to Сообщить someone on youtube?

There's this 10 или 11 год old girl on this one Хеталия video who literally wont stop trolling. She's been cursing, attacking, and even threatening people there in the comments. I saw her there months назад and I go back to the video and she's still there. Almost every single Комментарий someone post she Ответы back saying something like, "YOUR A RETARD!", или "NOBODY GIVES A SHIT!", или something insulting the show.

Ugh, she's not letting up at all. it seems that people in the Комментарии have been trying to ignore her but she seems to just get worse and worse with her replies.

Is there anyway I can Сообщить her at all? или contact the people who run youtube?
