Hello Folks, I am not quite sure this thread was not started before, but I believe it is still actual for lots of persons. So have anyone ever heard rules of submitting site in to social bookmarks? For what actions your website could get banned on bookmark website? What could increase your weight on forum? There should be some rules, and of course site owners do not run to place them, to stop gray-seos. And I am currently learning them by trial and error method.
