Hi to all white and Blackhat holders 3-4 years ago I had a website with phpbb3 (a forum) and i was used to see a lots of comment and registration spam there. I got page rank 2 without doing anything and all was duplicate contents.but from first date of that site it was attacked by spammers. Now recently i have made another one using wordpress and doing more afforts since page rank is harder now. I used to create lots of backlink and posing unique content! But i never got a spam comment or a registration!!! Why? I never installed any anti spam plugin as welll. Is that mean my site is not even worth to spam?
