Sometimes customers don't want to see certain videos or content from some specific Youtube-channels. These videos and channels can be added to block-list, so that content will not appear in Videoly widget. Allowing channels is often used for shop-videos. Content, marked as shop-video, means, that this video is created by the store. Some stores have their own channels. According to the rules of moderation, we have to add filters for such channels to allow this content on the store. Such mechanism is required to prevent shop's own content be presented in different stores for matched products.
