I think if you have a large youtube audience who's loyalty you depend on it would be wise to also have an external website (even a crappy 1 page thing) and link to that in every video. That way even if your videos are deleted you can stick them up somewhere else and link from your site and hopefully at least some of your followers will have bookmarked it.
