PM me if you have any Newgrounds-related questions, would like me to review your flash, or if you're curious about what I'm wearing. ;-)
Well, two things.
1. You can thank the Geometry Dash users for most of the reasons why we have such strict rules. They've upped audio theft so high Newgrounds has to buckle down.
2. I'm sure, if anything, a stat whore probably flagged your submission. Those people look for any reason to flag a submission to get points. Personally, I don't see a problem using non-commercial music.
Holy shit! You're finally back :D
It's the copyrighted songs contained in the videos. It's happening to a lot of content. Some of my favorite classics, such as dumbass Mario, are gone because of copyrighted songs. I heard it was BMI who started this shit, but I really don't know what to believe.
Glad to see you're not dead yet
Like others mentioned, it's the copyrighted content -- the swf files are still somewhere on the server; they're just disabled for access until someone can replace the music.
PS, if you ever come back, it's me, Andrea364
