I doubt many people realize that he is a young kid, living in Vietnam of all places (hint, not first world), who is taking his first steps in game-making. His simple 2-day effort blows up into a global phenomena due to PewDiePie and now he is a target of vitriolic hatred, press hounding him relentlessly, scammers latching on him trying to fleece money, and I am sure the Communist government is interested in his money too. Based on his tweets (for a long period of time before Flappy Bird), he is just a simple guy who wants a quiet life. Yes, he made enough money to retire (especially with the cost of living in Vietnam), but it is not his fault his game went viral. Green pipes are hardly going to land him in legal trouble.
There is no evidence of any bots or other under-handed tricks. But there is plenty of evidence that gamers are heartless, spiteful haters who cannot stand someone else becoming financially successful.
I mean look at these tweets aimed at him:
