Is it possible for scammers to add '<A rel="nofollow" >' into the code of ad_network.php ? Please address to my worry. Thanks.
Yeh, I guess I can see someone *thinking* that there would be an advantage, but as far as I know there wouldn't.
Would require someone to change the output of the ad HTML, which a a blanket rule would be against the terms and get themselves banned from the ad network.
Thanks Shawn. I hope you have a way to check such foul play. To those who *think* that they can read my mind, please don't get wrong impression. I ask this question not because I want to modify the code. Sheess...
I have seen this question before here and never saw the answer to the question...thanks for clarifying
