Having lived in Thailand 4 years I can say that posting "true and accurate" comments on a social website that may offend someone in the Thai government, police, army, or ruling elite could and has resulted in up to 15 years in a Thai prison, westerners included. There is a place for anonymity in freedom of speech and in revealing the truth. Mind you, there are many, many countries where one could end up in prison for just doing what you guys think is an every day thing.
