Based on the provided contexts, it seems that there is no current way to "whitewash" or bypass downloading Bilibili's "charging" exclusive videos for free. Bilibili has not yet implemented a way to verify the cookies of downloaders, and there are no known software or websites that can bypass this. The "charging" feature is a way for users to support creators and ensure their continued content creation. It's not a pay-per-video system, but rather a monthly subscription to a specific creator's content [2] [3] [5] [7]. There is a tool shared in one of the contexts, but it is for verifying the video, not for bypassing the payment [8].

Information is missing on any other ways to bypass the payment for Bilibili's charging exclusive videos.
