Can we have a mod mail to the user that posted a video about how the holocaust never happened?

The user has posted several videos recently, the one in particular I am referring to is about how the holocaust was a lie, this user also posts videos about how Hitler was a good guy, how the Nazis were good people, and the like. I believe this is a violation of the rules and it should be brought to the moderators' attention, so can we have a mail sent to the user?
