TemplatesBrowser.com/wordpress-themes/ is a WordPress theme download site, re-distributing hundreds of modified themes while piggy-backing the theme authors’ credit messages in the footer to link back to TemplatesBrowser.com.
Other than ripping off GPL and even Creative Commons themes, it isn’t safe to use themes modified by Templates Browser. They don’t simply link back to their own site. They also package encoded, hidden ads via the themes’
functions.php
files.
