<p>I refer you to <a href="http://meta.stackexchange.com/a/119711/131874">waffles answer over here</a>:</p>

  <p>Flag weight is now dead, you should decline flags that are not helpful and teach people how to flag in a helpful way.</p>

<p>Basically, people were not learning about bad flags because almost every single time a mod declined a flag, they would be berated by the person (ok, occasionally you'd get a request for constructive criticism, but they are few and far between), as the cost for a bad flag was massive compared the be reward for a good one.</p>

<p>I for one am glad to see it go, for the exact reason above. It wasn't worth the effort to decline a flag, because for someone like Iain, he had to flag <strong>92</strong> successful flags to undo <strong>one</strong> bad flag.</p>

<p>However, bad flags <em>are</em> also shown - in red in brackets.</p>
