At a friend's roleplaying game, who was doing a fresh take on the Megaman genre, she noticed a phenomenon where 'Tumblrettes', as she called them, rushed the game, started up activity, then migrated away en masse when the plot started to pick up. I don't think it's an deliberate conspiracy, but it's the fad mentality that takes down a lot of games. The thing you have to do is be careful where you advertise. I, for example, don't want to advertise on a game with a lot of anime fans, because my style clashes with anime, my inspiration is drawn from a lot of American science fiction literature with completely contradictory ideas about warfare, the government, theology, etc. I draw from Herbert, Clarke, or Heinlein, that's a different playset than, say, someone that wants a utopian soap opera.
