Something very similar happened to me too. They specifically focus on people who don’t have photos and they often scan through tourist locations like Times Square. They are looking for people who are likely closeted and traveling - more willing to experiment.
There’s a government hotline for when these things happen - but it didn’t do much.
they had a way to use my phone number to look up my family (likely from cell phone family plans?) and get addresses. They used Google Maps to send me pictures of the houses which was pretty scary.
They didn’t follow through on the threats but it was really upsetting. Sorry this happened to others.
