You might not understand this but...
The nature and original intended purpose of the Pligg CMS system makes Pligg powered websites a lot more of a target of Spammers! There are tools to fight this, using Global SFS, blocking the worst offending Pacific Rim IP addresses, a moderation system, Akismet, and internal spam triggers take care of a lot of spam.
One of the really big problems though is the 'Register.php' file which is the program that adds new users to the CMS from a form. Renaming this file helps but breaks the program unless the related system files are updated and the changes to the system files will then make the link to 'register.php' available within the form again.
What my next project will be is to 'fix' this so I can have a standalone register.php module that I can just email the link to any legitimate users who might need to register.
