Animation just isn't as plentiful in the fandom as a whole. There is enough interest in animation, but the amount of time and effort it takes to create a animation piece means there aren't enough animation works to fill a compilation compared to artwork and music works.
Therefore most animations we get sent in get featured in their own post.
That said, you might want to mellow your tone. Insulting others isn't going to help you get any more support for animation.
