Papers say 'data available on request' or link to files that no longer exist. Journals should verify data access at publication and periodically afterwards, and mark papers whose data have disappeared.
Studies of data availability statements find that most 'available on request' data cannot be obtained, and that links decay within a few years. Automated checks at submission (resolvable repository DOI, non-empty dataset, matching description) and annual re-checks, with an expression of concern for papers whose data become unavailable, would make data sharing real rather than nominal.
