if i submit ​run donnot use YouTube and others，but i use billbill be the video URL

so，will lead to an instant reject of the run？

no, somebody already use bilibili upload the run, although video already take down by bili offical, but the run time still valid

so，i can use it really?

yea, bili can, use it, here will not as platform to reject u, trust me, (and i speak in chinese so u can know what i mean easier) b站完全可以，你用就对了，这边不会因为平台不给过，信我就对了，(要了解更多的话可以去你评论区聊，我已经去发评论了，找ZhanShuBai这个名字)
