So I met this wing a while ago. He seemed like a pretty normal and cool guy in the beginning. However as time went on I noticed some strange things, like I noticed he would audio record our conversations without telling me. He's also recorded me on video approaching sets multiple times even when I asked him not to. He is in posession of several videos of me day game approaching on the street and my face is in full view. I am not sure what to think of this. By now he also has most of my personal details like where I live, my job, full name, and I've caught him staring at my personal documents trying to memorize the information. What damage can he do with this information? Should I be worried?
