ok why is this even allowed ? (housing)

Is it possible they bought the houses before restrictions were in place, and manage to meet the criteria to never lose them?

If you owned multiple houses before the restriction, I'm pretty sure you got to keep them. I'm not sure if that was retroactively enforced lately but that might be some of the issue. Because some people are probably grandfathered in at this point. But if there's multiple service accounts then you can pretty much bet that person is involved with RMT/botting. Especially botting--because that's the bottom rung of RMT activity right there.
