Have you ever noticed how over-night graffiti has appeared, of a purely political nature on the buildings around you, ..perhaps your house? Have you ever noticed individuals who appear on expat forums spraying the discussions with nonsensical and lengthy rants about how they hate the expat country in question? Have you ever wondered why they would even hang out on an expat site if they hated that country so much? Have you ever wondered, as someone else suggested, that these people were plants, being hired and paid?
