It can be removed, but you have to be able to edit the style sheets to the forum....
Here is the first thing to look for....
<div><div style="height:px; width:px;"><script type="text/deferscript"> <script type="text/javascript" src="http://partner.googleadservices.com/gampad/google_service.js"> </script> <script type="text/javascript"> GS_googleAddAdSenseService("ca-pub-8810354328358242"); GS_googleEnableAllServices(); </script></script></div><div style="height:px; width:px;"> <script type="text/deferscript"><script type="text/javascript">GA_googleUseIframeRendering(); GA_googleAddAttr("forumid", "42"); GA_googleAddAttr("loggedin", "true"); </script></script></div></div> <div id="main-container" class="semi-fluid">
<div id="header">
<div id="header-area">
<a class="header-logo" href="/">Saltwaterfish.com</a>
<div id="header-ad"><div style="height:90px; width:728px;">
<script type="text/deferscript"><script type="text/javascript">GA_googleFillSlotWithSize("ca-pub-8810354328358242",
"SaltWaterFish_Forum_728x90", 728, 90);</script></script></div></div>
</div>
The Google Adsense stuff is your culprit, I didn't dig to see if there is any other advertising going on, but removing the google stuff is a big start.
Don't worry so much about your google placement, removing the adds creates a faster, cleaner forum, if you still want to keep your page rank on google just allow the search engine bots permission to crawl the forum.
