That's possible, though from the girls I met I wouldn't guess that was the case. I'd say it was just some entrepreneur, possibly an ex-escort renting the rooms out to independent women.
And if they were being forced, well how do you know the women you've been with aren't forced. If they seem happy making 200 an hour maybe they are.
Either way the gardai did nothing to stop them escorting, their profiles came up a few days after it happened in different counties.
