Of trolls and provocateurs

What do you folks think? Could there be trolls and provocateurs lurking here in IN International forums to do their stuffs - that's to spread propaganda and help to bend minds for their masters? What do you think? We already know there are scammers and fake profiles as well as there have been numbers of excommunications of members by IN. This is after all an arena for everybody to "peddle their wares". There are a number of NGOs that exist to further political, religious and social agendas and aspirations. Could they already have their reps here?
