Child abuse or classic movie?

Cybertip.ca keeps emailing us @ imgsrc.ru regarding a screenshot made from this (obviously 100% legal classic) video: https://youtu.be/1v6msu_Dl0U?t=82

This is what they say: Cybertip.ca is Canada’s national tipline for reporting the online sexual exploitation of children. Cybertip.ca has become aware of content depicted on your service that is sexual, harmful and/or abusive involving a child. A child is defined as a person under the age of 18. We believe the content is abusive and/or harmful to the child in the image, and violates the child’s basic right to dignity, privacy, and safety, rights that are afforded to all children under the United Nations Convention on the Rights of the Child (UNCRC). The content may also satisfy legal definitions of illegal material in some countries. It is our position that it is not in the best interests of the child(ren) depicted for the content to remain publicly available and we are requesting that you remove it from your service.

Can we believe what they believe for? Or is cybertip.ca becoming another SJW scam now?
