It doesn't even look like an AD, but part of the text, Are they CHEATING?

I'm doing biology research and I came across this site!
http://www.biologyreference.com/Po-Re/Protozoan-Diseases.html

Take a look at it!

Is that a special form of "adsense premium" ads or something?

They tricked me!

Take a look at source code:

<!--
function google_ad_request_done(google_ads) { var i;
if (google_ads.length>0) document.write("Ads by Google<br>");

for(i = 0; i < google_ads.length && i < 3; ++i) { 
document.write('<br><a href=' +
google_ads[i].url 
+ ' onMouseOver="window.status=\''
+ google_ads[i].visible_url
+ '\'; return true"'
+ ' onMouseout="window.status=\'\'; return true"'

+'>' + '<b>' + 
google_ads[i].line1 +
'</b></a>'
+ '  - '

+'<a class=\"blue\" href=' +
google_ads[i].url
+ ' onMouseOver="window.status=\''
+ google_ads[i].visible_url
+ '\'; return true"'
+ ' onMouseout="window.status=\'\'; return true"' + '>'
+ google_ads[i].line2 + ' ' + google_ads[i].line3 + '</a>'+

' (<font size=\"-1\"><a class=\"red\" href=' + google_ads[i].url

+ ' onMouseOver="window.status=\''
+ google_ads[i].visible_url
+ '\'; return true"'
+ ' onMouseout="window.status=\'\'; return true"'

+ '>' +
google_ads[i].visible_url +
'</a></font>)<br>'
); 
} }

// -->
</script>

<script type="text/javascript"><!--
google_ad_client = "pub-5788426211617053";
google_ad_output = "js";
//--></script> <script type="text/javascript"

So... What is this? lol

 

Looks like a premium publisher to me.

 

Nice blending, probably pemium pub.

 

or another trick to manipulate adsense which against google TOS.

 

That looks nice, I wish I can have ads like that on my sites. I'm not sure they are premium publisher. According to Alexa rank that site doesn't have much traffic.

 

A publisher can have more than one site

 

With so less traffic to their website, how did they manage to get a premium account?

 

Premium Publishers don't necessarily need to be a company, can be one individual acknowledged by Google AdSense worthy of receiving premium status.

I've seen a couple other sites that modified their AdSense code to look like actual information in tables (I think it was Dell or some other computer company).

 

I cant understand why Google is not allowing this to everyone? It helps them, it helps the small publishers..... so what is the problem in giving this feature to just premium publishers?
