I were playing with the Wayback machine on newgrounds... And I have been very surprised by something. An user (named @murgee) have published some musics in 2015, and had the chance of having the 3 first submissions appearing on the main page of the website.

But after researches, I found that all of his audio have been deleted by the moderation team (like http://www.newgrounds.com/audio/listen/658706)

My question (do not search to answer it, it'd be too long, but just in case you'd have an idea) is : Why ?
