I submit an anime and got reject because the anime is not approved in mal. But site have animes that MAL dont have approved yet so why this is diferent?

If you only submitted the MAL id number, then we couldn’t accept it if the anime on MAL is still pending approval. Not every anime in the database has a MAL id attached, but for it to be added the MAL entry in question needs to be officially approved by MAL.
