I was once hacked, stalked and targeted by friends of a celebrity who I had just met. I tried pursuing help about it and was threatened with murder. Then, after promising to report the murder threat, I was told by another person in that social circle that if I talked about the previous incidents that my career reputation would be permanently ruined.
The last person told me in the same conversation that Peter Thiel would recognize him. As Mr. Thiel has many interests, there was no reason to believe this person was connected to Palantir. However, Palantir sure came to mind while I processed this last interaction like a deer in headlights.
I can only speculate, but it was during the course of a reference check for someone connected to this circle. So, likely this was done to look into me, demonstrate power over me, and let me know they are "watching".
many celebs have personal protection details. how such protection details behave likely varies widely..
as for your concerns, pay close attention to your cybersecurity posture before engaging with people who will draw attention to you simply by association.
