It's always been there. Back before they nerfed fame / 10, Tarakan still had a few billion. I don't know what the breaking point would have been, but that's why they nerfed it. I'm guessing it was a band-aid nerf and it could theoretically happen again if someone pushed their fame high enough, but it would still take a pretty long time. I wanna say Tarakan was at around 3 billion at the time they nerfed fame, and supposedly Kaedra had like 3.5 billion at the time she quit.
