@RalseiGD You must contact with one via PM - here you a link which contains a detailed list of all the current active members of the Newgrounds Moderation Team:
(https://www.newgrounds.com/wiki/help-information/site-moderation)
Make sure to focus on the Audio Portal Moderators section, as blambi specified - the rest of Moderators won't be able to help you in this case, since they dedicate to other areas of the site.

Newgrounds removes copyrighted and AI music (like Suno). Talk to an audio moderator if you think there was a mistake.
