From the guidelines:
&quot;If you think a story is spam or off-topic, flag it by clicking on its &quot;flag&quot; link. (Not all users will see this; there is a karma threshold.)&quot;<p>&quot;Off-Topic: Most stories about politics, or crime, or sports, unless they&#x27;re evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they&#x27;d cover it on TV news, it&#x27;s probably off-topic.&quot;
