While I generally disagree because I'd rather my site was the one getting the hits—and I would rather give the same courtesy to other authors—this does give me the idea of checking (or creating if none exists) an archive link of whatever I reference, and include that archive link in the metadata of every link I include. Users will find the archive link if they really want to, and it will make it easier for me to replace broken links in the future.
