Damn right it's not.
But it's a matter of perspective. Having given it a bit of thought, I realized that much of the music I listened to as a kid in the '50s on the radio or TV is already here.
How can I have my generation's kid's music on the site, but deny the millennials theirs? Seems a bit unfair. So I tend to let it go.
That said, there's also a furry/brony aspect to many of these that imply particular fetishes. That's pretty twisted. And I approve of twisted. Unless this singular fetish attempts to dominate the site. Then things are going to start getting deleted.
If there's a bit more self control, it will remain ok.
