Been fighting a bunch of spam posts on http://www.PullersvilleUSA.com
Pullersville USA is a Pligg powered site. Pligg sites are targeted by spammers a lot but my configuration includes several systems that should slow that including a new post moderation system, Spam Traps, Pacific Rim IP blocking, etc.
Finally went back into basic configuration ande there was the problem staring me in the Face. I forgot to set the ‘Validate user email’ setting which requires users to validate their email address. Should have been set to ‘True’.
Anyway, I work on and can install Pligg based sites if you need someone to build you one. I also build and install Web Based Forum Boards, WordPress based CMS, Multi Site wordPress, Store Fronts, auction, Classified Ad sites and Link Directory systems.
