Does anyone associated with the admin of MG make copies of uploads that are located in other places because of size restrictions here? If not, I think it should be done. In that case, if the original uploader no longer participates in MG, and their link goes dead for whatever reason, and no one else has downloaded a copy, then at least we have a copy to reupload. The MegaUpload debacle is severe case, but a link can cease working for other reasons. I think we should try to protect what is already uploaded if it is practical to do so...but maybe that is happening already?
