Why top sound effects share only few categories?

Sound effects have a lot of categories, but on populars people can see just a few of them.

No buttons/menus, no toon sounds, no domestic, no game sounds e.t.c

So as i unerstand if sound designer want to be in top he must mark his sounds "properly’.
But what about if i want to categorise my items properly instead of “properly”?

Is envato going to do something with this crappy categorising?
