I&#x27;m reluctant to say that paywalls with <i>no</i> workaround should be banned outright, but obviously they&#x27;re not covered by the &quot;ok&quot; policy.<p>Sometimes people post these and others respond with links to freely available versions, or articles about the work. In such cases we&#x27;re happy to update the URLs.<p>We&#x27;re not happy about announcement mills either (and those sites are penalized on HN), but that&#x27;s arguably a separate problem.
