I'm trying to imagine the sort of system where a migration from "human" to "group" accounts results in a flag for fraud on that account. It's giving me nightmares. Surely they are more competent than the code/architecture I'm imagining it would take. I'm going to hypothesize that this isn't a technology glitch. It seems more likely that the move triggered a look at his account by some human who for reasons that are unknown to us decided his account looked fishy.
