Just one question about Bookmark Demon, I don’t undesrtand on thing … :

In the PDF « gift » you get when you subscribe to the Bookmark Demon form, it says that if you send the same content
to 100 bookmarking websites (I’m not talking about spamming, just ONCE, same content to 100 websites), you could
have penalties because it could be consider like duplicate content...?!

Is it true or just a argument to make us buying their services (they have the option « rotative content ») ?

Thanks !
