Okay, so I has trying to create a track called "1c1 - hyper", but as I was trying to publish it, Newgrounds suddenly flagged it for copyright.

Apparently they said I copied from this song called "Un Estate Al Mare" by J.Dee Project

I checked it out and they sound nothing alike

I used Beepbox to make hyper, which allowes you to use the sounds to make any track you want, and put it under your own licensce, and Beepbox does not claim ownership over anything in your track.

Ive never even heard of J.Dee Project before, or any of their music.

They have even put my account on hold, so I cant edit anything. (Edit: I can still edit some things, as well as publish things that aren't audio)

I sent a case back, to show I didnt copy anything, but is there anything else I should do?
