Your best defense against exploits on trader pages is feedback from your visitors. When a visitor clicks a link (via out.php), the script logs where they were sent.
Place a link like this next to each link
<a href=”/?gallery_id=<!--GALLERY_ID-->&force_template=content_report”> Report Bad Site </a>
When clicked on this URL, the surfer will see a report form, and you will see the results in Cheat Lookup → Reports.
The report template is in Rotation - CMS.
