As far as I'm aware none of my music is particularly rare. I'm mostly referring to video content creators have decided no longer suits their public persona and have deleted, or was taken down by legal threats or ToS violations. Also some web pages and web comics that have gone offline without making it onto the Internet Archive. Now that I think about it much of my porn archive would also be difficult to locate copies of, though that isn't nearly as organized. Basically if I like something I keep it forever.
