Usage:

[adfly]{SIMPLETEXT1}/{SIMPLETEXT2}[/adfly]
 
HTML Replacement:

<script>
 var adfly_id = {SIMPLETEXT1};
 var adfly_advert = '{SIMPLETEXT2}';
 var frequency_cap = 1;
 var frequency_delay = 5;
 var init_delay = 3;
 </script>
 <script src="http://adf.ly/js/entry.js"></script>
 
I hope somebody will find this useful. It can be good for protecting quality content.
 
For {SIMPLETEXT1} you would put your Adf.ly ID, for {SIMPLETEXT2} you would put either int or banner for interstitial or banner ad type.
