Try editing the editor_on template and change this area near the end:

<table cellpadding="0" cellspacing="0" border="0" width="100%">
		<tr valign="top">
			<td class="controlbar">
				<textarea name="message" id="{$editorid}_textarea" rows="10" cols="60" style="display:block; width:$stylevar[messagewidth]; height:{$editor_height}px" tabindex="1" dir="$stylevar[textdirection]"><if condition="THIS_SCRIPT == 'infraction'">Proof:

Link to Rule:</if>$newpost[message]</textarea>
			</td>
			<if condition="$smiliebox"><td class="controlbar">$smiliebox</td></if>
		</tr>
		</table>

I haven't tried it yet, but try it on your test site and see if it works.
