I wonder if these scams have actually happened in Japan, or if they're mostly fictional (by stitching together real crimes, for example).
Like, I can imagine dudes giving out loans to desperate women, and I can imagine dudes paying desperate women for sex... but I can't really imagine women accepting a loan AND also giving sex to the dude.
Likewise, this scam seems so elaborate for what scammers usually try to do.
I can imagine a group of individuals pretending to be a charity to get survey information that they can use to steal identities, but I can't imagine such a group existing to sell that information to information brokers, and government officials to use said info to cheat the system.
I suppose that's the writing of this series - taking dull normal scams, and adding a few flares to them to make it a more interesting read.
