There is none. You'll have to edit the template and also add some CSS. In postbit(_legacy) find:

<div class="postbody">

Change to:

<div class="postbody <vb:if condition="$show['moderated']">moderated</vb:if>">

Then add some CSS to additional.css like:

.postbitlegacy div.postbody.moderated {background: pink;}
