Bachus--happens every so often. I haven't seen it in person, but some locals complain privately about it (citizenship is exclusive here, and trading on it is a perk). On QL it is endemic. I suppose people do it for the same reason unempowered people try to "pass" as the ethnic group in control in every culture. I am white, male, from a Western country and financially prosperous by anyone's standard, which by default makes me part of the privileged group, so I am just speculating. I am sure the bitter baazigar can offer first-person testimony.
