I don't think entities can easily identify and track a person
Because what happens during this type of interaction is through consciousness, not the personal body ...
Perhaps it is impossible at all to know the person unless he allows it and invited him to meet him
Also the issue is difficult, it seems to me that there is a law and an organization that manages the universe or our galaxy.
It has laws at the general level.
There are those who violate it, but in a mysterious way it is not apparent to be condemned, and this matter revolves around the field of ideas, beliefs, psychological motivations and spiritual connections..
