Sadly, if someone wants to find information there is enough online without needing to help them with social media. My parents have never had a social media account and I deleted mine years before I had an issue with someone who found out not only where I lived but my parents as well. (and having 20+ years in the software industry, I'm aware of how things work). Doing a simple search isn't that difficult to get the addresses. Though, it was probably a tracking device and considering the later disabling of important drive functions that my long time mechanic had no answer for except to not charge me hours of work looking at it and telling me to just get what I could for it, I lean towards tracking device. Staying off social media helps, but when someone wants to harass another, I think not being easily online just made it more fun for him. At least I would find the challenge more gratifying.
