Many people say there is absolutely zero aggregate difference amongst various countries in terms of both governance and culture. Could something like this, on such a scale, actually fly in a western country?
Many online gambling and adult entertainment companies operate and are based on very scammy business models. They deliberately seek to identify and target "whales" who have behavioral addiction problems that can be exploited for money. (although I would argue that internet porn is a legitamate and useful service) In the opinion of many, Zinga was (and is?) a very sleazy and unethical company.
More broadly, there have been many many massive financial frauds in western countries. Dietary supplements, sub-prime housing, madoff investments, the list goes on and on. If anything, the "non developed" world might be more honest than the developed world.
