Are people abducted and taken to Nibiru by the Anunnaki, and by Arcturians to their planet or another planetary location, in addition to the Reptilian slave colony?

There have been many removed in the past by the Anunnaki, but this has not been done in recent times. It is done when they come into closer apposition with their planet and the travel is increased. The Arcturians as well do not maintain humans within their own home planet as they regard us as inferior and have no need of our services. They have many hybrid Greys as minions to do menial tasks and to serve their needs. So this is largely a Reptilian operation at this point.
