We were just checking out backlinks on a site that was using Simple RSS Feed Reader at ahrefs.com. Turns out porn sites are trying to use redir.php links on their sites. For example: www.lifechurchstlouis.org/modules/mod_jw_srfr/redir.php?url=https://pornaaa.com . The file redir.php doesn't do anything except type "No direct access." Since the file doesn't do anything, why is it in the module? We are going to remove it so that these links give a 404. We advise you to remove it from the module.
