I was going to start a poll about it, but I wanted to get an idea what people thought about it first.

I usually keep a copy of videos that I sift which I know are going to get pulled for whatever reason (copyright etc). I also keep copies of other sifters clips that I like or are very popular if I think they will get pulled.

It would be a lot easier to fix dead videos if we could just host it ourselves and fix it without it being considered a self link.
