<p>I think the automatic locking by the Community user is somehow to do with migrations of a question from/to this site being rejected. The rules Community follows have changed over time&mdash;see <a href="https://meta.stackexchange.com/q/35744/225179">Allow diamond moderators to reverse question migrations?</a>. Anyway, please feel free to flag any such questions you think should be deleted &amp; ask a moderator to delete them (I'm having trouble imagining situations where it'd be useful to unlock them just to allow down-voting).</p>
