As previously stated by myself and many others, Pligg can be a major SPAM magnet if you let it become one. There are ways however to combat this, namely reCaptcha.  

Want to keep people from viewing and stealing your template files? Of course, we all do. Here’s a simple way to keep prying eyes out of your template files and stealing your layout and functions.  

One of the biggest issues with the Pligg CMS is SPAM.  As a Pligg powered website owner you are constantly dealing with submissions of links that are blatent spam, spam bots and spam in the comments.  To be fair, Pligg is not the only CMS that faces this issue, but it does have very little deterents in place to prevent it.  

The latest release from Pligg v1.0 came with a lot of promise. New features, a new admin panel and what was belived to be a more stable version. This sadly is not the case.  

A while back the developers setup a store where members could purchase modules and templates, this was to help the team with costs. While I have no issue with Pligg selling modules, I do have an issue with them selling modules that have no business being sold.
