Hi David,

You can hide the notifications that appear above a post in the system by comment out the code below in the file:
JoomlaFolder/components/com_easysocial/themes/wireframe/stream/default/item.php

<?php if ($stream->hasLastAction()) { ?>

			<div class="es-stream-header t-text--muted">

				<i class="fa fa-clock-o"></i> <?php echo $stream->getLastAction(); ?>

			</div>

		<?php } ?>

and see how it goes.
It can be done by do template override as well

You're suggested to backup the file that you want to edit beforehand for precaution
