There's a specific removed video that I want back (the whole channel seems to have been bought by someone who wanted pre edition subscribers or something, then everything on it was nuked and replaced with content that doesn't interest me). I tried emailing the channel's new email address to ask for it, and got no response. Do you know of any practical way to try to get it back?
