I'd doubt it. Most of the leaders in this place aren't the brightest tools in the shed, and, given how they can't distinguish us from actual trainers seems to imply that we're either here by accident, that they're too dim to massively kidnap hundreds, or everyone is good at playing dumb. Though, team rocket might provide some interesting leads. Perhaps they're the masterminds, but that wouldn't explain why some people arrive in a location different from their base.
