Unfortunately, psychics can't filter the info that they get, even if it may seem annoying or unnecessary for the asker. I also sometimes get this when I read my own cards or for others. I had stalker guys and unwanted exes coming up in a reading and I literally want to bang my head to the wall when such thing happens.
If another person is stalking you physically or mentally obsessing over you, the cards/tools will pick it up and they will pop up in the reading instead of your POI because simply the energy of this particular person is much stronger than let's say a POI who is not keeping tabs on you or is with someone else/has other things to distract himself. It's very annoying but it happens...I haven't personally found a method of avoiding this altogether...it still happens occasionally.
